While still alive, at his physical peak, Mogami was a regular looking man with flat dark coloured hair and small lines under his eyes. He normally wore a white shirt with green pants and a green blazer. As he got older, his age and world-weariness were visible as he started getting wrinkles.
As a spirit Mogami took on many different forms. For example, when confronting Mob for the first time in his mindscape he appeared just as he did as a human. However, oftentimes this form was underlined by hollow cheeks, dark eyes, and sluggish posture. While watching Mob in his artificial world he would manifest as different small animals such as a crow, a moth, or a caterpillar to spy on him. During his battle with Mob he also appeared as some sort of ghostly wraith of dark green smoke with red eyes, and later as a being composed completely of red and black energy. When he was released from Matsuo's canister by a Claw soldier, he briefly took on the form of the shadow of the girl he possessed, Minori Asagiri. He also temporarily created a massive tree-like body for himself out of Minegishi's plants at one point.
Originally, Keiji Mogami appeared to have a very aloof and content personality, pleased to help whoever he needed and remove any evil spirits who were possessing innocent people. However, he was doing this while being used by many of his employers, and this began to build up negativity inside Mogami. Eventually, this negativity manifested around him, affecting his mother and making her ill. After this, Mogami's morals faded when he was forced to assassinate people in order to get enough money to pay for his mother's bills. Once his mother died and she came back as an evil spirit to inform him that her illness originated all the negativity brought by Mogami, and that his job as an assassin was only making it worse. From this point on, Mogami's faith in humanity significantly deteriorates, and he is determined to gather enough spiritual energy so that when he returns as an evil spirit, he can exact revenge and punish everyone who uses others and believe they will never face justice due to their power.
It is because of this that Keiji Mogami is a very bitter man, sick of the greed and selfishness of humanity. Because of the private dealings he did while alive, he has lost his moral compass and has become a twisted variant of his former self. After becoming an evil spirit, he vowed to use his power for his own intentions and fix the world by possessing people who appear to gather grudges around them. In this sense, he can be considered an anti-hero, since he punishes corrupt people who abuse their power but still uses unethical means to punish them. However, this hatred and anger against such people develops to the point that he is willing to defeat and nearly kill several hundred psychics who he believes are simply phonies and greedy people without knowing anything about them. Additionally, his morals have become so twisted, Mogami is willing to destroy a young girl's body and brutally impale her father to achieve his whims.
Despite this depravity against many people, he appears to have a soft spot towards Shigeo Kageyama. Upon seeing the unimaginable power he possesses, he decides to bait him into Minori's body, and tells Shigeo that he's never met anyone with the power he possesses, saying he is truly blessed. After reading his emotions, he realizes that he allows other people to use him and sees himself in him, so in order to try and steer him away from the path he went on, he puts him in a mindscape for six months where he has no powers and has to see the world in a different perspective. He nearly breaks Shigeo, but after Dimple enters the mindscape and reminds Shigeo of who he is, Shigeo snaps out of his original vengeful state, enraging Mogami because he couldn't fully turn him. After a very hard-fought battle, Mogami is eventually defeated, but instead of being angered by his defeat, he accepts it and decides to look at Shigeo's life transpire to see if his decision was the correct one. This demonstrates a sense of possible regret towards his previous answers and allowed him to regain some faith for humanity.
However, he is still very hostile towards power-hungry individuals, and after being released from Matsuo's control, is prepared to kill Minegishi, and nearly does so until he's stopped by Shigeo. He tries to tell Shigeo that there are people who never change, and that Shigeo is being naive if he thinks he can watch over them to make sure they don't do anything bad again. Alas, Shigeo says that people need to have faith in one another in order to function in society. After hearing this, Mogami lets Minegishi go, but tells Shigeo that it is necessary to be hard on people sometimes, and if he can do that, he will be invincible. From this point on, his whereabouts are unknown, but it's suggested by Dimple that he's moved on to the afterlife. This indicates that Mogami may have finally let go of his hatred against the underbelly of humanity and accepts that Shigeo is correct in his faith in humanity, finding peace within himself as well.
Mogami was born with the ability to see ghosts and other powers people dreamed of, so he initially did the world good by giving advice and helping people with their problems. To that end, Mogami became one of the most famous psychics and was the first psychic to be on Japanese television. However, his mother suddenly became gravely ill and the treatment was very expensive, so Mogami needed money. Due to this, outside of the spotlight, he would take on assignments from clients to solve their supernatural problems and would even take assignments from the underworld to lay death-inducing curses on others. Despite the morally dubious assignments he was taking, he continued taking them in order to pay for his mother's treatment. His mother eventually died, returned as an evil spirit and revealed that the reason she died was because all of Mogami's actions had gathered "demons" around him, which meant that she suffered.
Since he no longer needed money, he stopped all his business with the underworld. Pondering the how much of a waste his life had been, Mogami resolved to fix the world and travelled around consuming evil spirits to cultivate his power for when he would eventually become an evil spirit. At one point, he encountered Dimple's group and annihilated them, with Dimple just barely escaping. He committed suicide 25 years prior to the start of the series (40 years in the anime), becoming a powerful spirit in the process so that he could torment the "evil people" of the world.
Keiji Mogami Arc
One of Keiji Mogami's attacks included entering the wealthy businessman Masashi Asagiri's mansion and possessing his daughter Minori Asagiri, a callous and spoiled girl whose troublesome behavior irked him. Masashi was forced to seal Minori in a protective room and lock her into a bed.
Masashi eventually hires literally hundreds of spirit detectives to help his daughter, including Reigen and Mob. When Reigen enters the cell to talk to her, Mogami tries to get him to believe that Masashi is the one who's been possessed and is acting irrationally - this convinces many of the exorcists, but not Reigen. He notices inconsistencies in Minori's speech, such as odd changes in tone of speech and knowing Reigen was a psychic before he even introduced himself as such.
With his act being exposed, the Mogami-possessed Minori breaks out of the cell, and Dimple recognizes him from a previous fight and warns Mob. One of the espers, Kirin Jodo, attempts to exorcise Mogami from Minori's body, but Mogami is able to effortlessly stop him, deriding the esper for his pathetically weak abilities. Possessing Kirin, he attacks the espers, but Reigen strikes Kirin with a strong knee to the stomach, forcing Mogami out of Kirin's body. Several exorcists try to exorcise Mogami and fail miserably, and one of those exorcists is Banshomaru, who uses his Spirit Bind to trap Mogami, but he ables to break free and attacks the esper. Before he can attack, he is stopped by Mob, and Mogami notes that whoever is stopping him has decent telekinetic abilities. However, Mogami begins breaking Minori's body against the force of the telekinesis and forces Mob to let go of her. Mob attempts to force Mogami out of his body, which he is temporarily successful at doing, but when he unleashes a powerful psychic blast, Mogami goes back into Minori's body. The power from the psychic blast only serves to increase the psychic bond between Mogami and Minori, with Matsuo noting that they've almost fused. Mob realizes he can't exorcise Mogami from Minori from the outside, but if he is to astral project into Minori's mind, then he could have a chance. He temporarily lets Dimple have control over his body while he sends his spirit into Minori's body.
Mogami encounters Mob in a form similar to his human appearance, explaining that they are in a mind-based world of his own creation inside Minori. Mogami fires a psychic blast to test Mob's powers, and Shigeo is able to block the blast with a psychic barrier. Mogami notes this and is impressed. The evil spirit attacks Shigeo again by using a psychic technique to choke Mob. The esper is quickly able to break free of Mogami's control, and fires several bright energy beams that pierce through Mogami's body and dismembers his body. Now bloody and weakened, Mogami notes that Mob is the most powerful esper he's ever seen, and that he is truly blessed. Despite being overpowered, Mogami turns the tables on Shigeo and reveals to him that he purposefully allowed Shigeo in here to test him and to change his view of the world. Mob is powerless to fight him and is subdued, being placed inside a world identical to the real one where he is tormented and mistreated by brutal and uncaring versions of real people in his life, including Minori herself.
Over the course of what seems to be six months for Mob, he is tortured while Mogami sends him subliminal messages, eagerly waiting for the boy to crack and become another malevolent soul like himself. It comes to a breaking point where Mob momentarily agrees and attacks the artificial Minori and her friends with his psychic powers, but Dimple enters the mind world as well and snaps Mob out of it. Mob realizes his mistake and begins to tell Mogami of the err of his ways. Infuriated, Mogami releases the legions of evil spirits he has assimilated over the years to attack Mob, who reaches 100% Courage and fights them off in a battle that tears apart the very fabric of the mindscape. Mogami himself personally attacks Mob, but is defeated in a powerful psychic blast. However, his evil spirits go ballistic without Mogami around to control them, and they brutally gang up on Mob again. Mob's ???% mode is initiated due to the stress and ???% completely erases the mind world, freeing Mob.
Back in the real world, the weakened Mogami leaves Minori's body in an attempt to flee, but is captured in a film canister by Matsuo. Matsuo would go on to name Mogami "Pudding-chan" and keep him as a dangerous last resort weapon. During this time, he would watch events that transpired despite being trapped and eventually regain his strength to the point that Matsuo wasn't able to control him.
World Domination Arc
When Matsuo appears to help Mob fight against Minegishi and a group of Claw soldiers, Mogami's container falls out of his jacket. Despite Matsuo's protests, one of the Claw soldiers breaks the container, releasing Mogami. The powerful spirit sucks the life out of the Claw soldiers, and while he's doing this, he derides Matsuo for trapping him and now wanting him to consume a horde of espers, marking them as lowly creatures. Minegishi wonders what he's looking at and attacks Mogami, but Mogami uses his psychic powers to override Minegishi's signals to his plants and uses his own plants and chunks of concrete from the ground to form a massive tree-like monster.
Mogami uses the monster to grab Minegishi, raising him into the air and slowly crushing him. Before he can finish him off, Shigeo tells Mogami to stop. Mogami asks Shigeo why he's asking him to stop, remarking that he's seen all the events transpire and has concluded none of them deserve to live. He goes on to say that there are humans who never change, but Shigeo argues that they could change. Mogami challenges Shigeo's argument, saying that it is impossible to watch over people forever to make sure they are determined to change their ways. Mob concedes this point, but still says that it is necessary to have faith in people that they will change in order to function through life. After hearing this, Mogami lets go of Minegishi, showing he has come to respect Mob for his noble nature and faith in humanity, but tells Shigeo that it is sometimes necessary to be hard on people. His final words are saying that if Shigeo can do that, he will truly be invincible. Mogami vanishes, leaving nothing but a large tree in his absence. His whereabouts after this incident are unknown, although Dimple suspects Mogami passed on for good.
Powers & Abilities
Mogami is one of the most powerful characters in the series, rivaled only by Mob and Toichiro. When he was alive as a psychic, he effortlessly defeated full power Dimple, a high-level evil spirit; and as an evil spirit, he easily overwhelmed Minegishi, one of the Ultimate 5. Mogami left such an impression on Dimple that Dimple suggested to Mob and Reigen to just leave when he found out that the evil spirit they were dealing with was Mogami. Although false, when Mob failed to exorcise him from within Minori Asagiri's body, Mob even claimed that Mogami might be stronger than he is. Despite all this, Mogami was eventually defeated by Mob at 100% Courage.
As a spirit Mogami had the ability to possess people and take over their bodies, similar to Dimple. Like Dimple, he greatly enhances his host's abilities and he can also use his own while inside. He can root himself inside his host's body so deeply that even espers of Mob's level cannot touch him.
Mogami has a degree of skill in hand-to-hand combat, as shown he he was possessing Asagiri. He was able to get the upper hand against Dimple, who was possessing Mob.
Although Mogami never had telekinesis while alive, he obtained a very similar power after he became an evil spirit. He can shatter windows, fling people across rooms, and even choke people from a distance.
While possessing Asagiri's body, Mogami was able to create a mental world where everything inside was under his dominion, even Mob's psychic powers. Using Mob's memories, Mogami simulated a reality where Mob never had psychic powers and Asagiri transferred to his class; he claimed it to be an accurate depiction of what really might have happened, if Mob's circumstances were different. The inhabitants of the world were all evil spirits and Mogami himself manifested as various animals and insects. The anime added a dark filter and letterboxing to differentiate it from the real world.
Mogami can control the evil spirits that he has absorbed over his lifetime; however, there is a limit to how many. He used them to attack Mob in the mental world.
Mogami possesses the ability to forcefully drain the life force of those around him. He did this to the artificial espers of Claw after being accidentally released from Matsuo's container.
Mogami was able to usurp Minegishi's control over his own plants. He then used them to create a body for himself, similar to Wriggle Wriggle.
Mogami's Evil Spirits
Having absorbed them over his lifetime, Mogami's spiritual body was home to an unimaginable amount of malevolent souls. He collected so many that even he cannot control them all, and can only manipulate them if he releases them little by little. When Mogami was defeated by Mob, all the spirits inside him were unleashed and went out of control. The combined might of every single evil spirit was capable of overwhelming Mob at 100% Courage. They were swiftly defeated by ???% afterwards.
|Evil Spirits' Abilities|
The evil spirits can combine into larger spirits.
The spirits can also launch energy beams. When enough of them are together, a single blast can devastate the fictitious Seasoning City of the mental world.
- "You cannot solve all problems with your kindness. Sometimes, you need to be strict to others."
- In the manga his death takes place 25 years prior to the series, while in the anime it is 40 years.
- The berserk evil spirits can be considered Mogami's equivalent of ???%. They were unleashed when Mob destroyed Mogami's vessel, and ??? was unleashed when the evil spirits destroyed Mob's vessel.
- The berserk evil spirits are the only opponent that defeated Mob at 100%. Toichiro Suzuki came close but his fight against Mob got interrupted by him self-destructing, resulting in a draw.
