Ryo Shimazaki

Ryo Shimazaki (島崎亮, Shimazaki Ryō) is a powerful esper, member of the now defunct terrorist organisation Claw and a former part of the Ultimate 5.

Appearance
He has spiky hair with a few strands astray over his forehead, heavy eyebrows, sharp nose and pale skin. He wears a dark colored suit jacket with black shirt, pants, and shoes. He often wears a smile and his eyelids are usually closed but when they are opened they reveal that he does not have eyes.

Personality
He was only following Toichiro Suzuki around because it sounded like fun.

History
Not much is known about Shimazaki, although in the omake First Meeting, he appears alongside Minegishi to celebrate Serizawa's welcome party, implying they were already part of Claw three years before the story started.

World Domination Arc
When Shimazaki first appeared, the Claw leader Toichiro Suzuki informed him they were executing their plan and he then proceeded to kidnap the president. He was then attacked by Teruki Hanazawa who briefly took his interest with his array of abilities, before Shimazaki defeated him and left.

When the resistance group were traversing through the tunnels to the Claw HQ, Shimazaki encountered them and quickly defeated them all before returning to the HQ. After returning, Tochiro immediately told him to deal with his son, Sho. Exasperated, he left and encountered the duo of Sho and Ritsu. Ritsu took Shimazaki on instead, with the latter allowing Sho to pass, but their bout was one-sided in Shimazaki's favour. Just then, the rest of the resistance group arrived and they all took him on in tandem.

However, despite their overwhelming numbers, Shimazaki made quick work of most of the group and got ready to finish it up. After a discussion between Teru and the group on needing to distract Shimazaki to win, the latter decided Teru was the biggest threat and concentrated on attacking him to break the group. However, before he could defeat the teenager, Teru began countering his moves after catching on Shimazaki's tendency to attack his enemies from behind after teleporting.

Shimazaki expressed his surprise at how Teru is still able to withstand his blows, claiming himself to be the strongest in the world after his boss Toichiro. Teru laughed in response, and argued of how small Shimazaki sees if he thinks their fight is the world's best. The young psychic remarked how Shimazaki is just as much of a commoner like himself, which got Shimazaki angry. However, the discussion between the two served as a distraction long enough for Ritsu and the rest of the group to attack him with their combined esper abilities.

Losing his advantage against the group and accumulating more injuries in the process, Shimazaki tries to focus on heightening his extrasensory sight to try and escape his situation as he continuously keeps getting beaten. This action pushed him to the point of seeing only the espers' aura within his range, awakening to his "Mind's Eye". Shimazaki then decided it's time to get serious and proceeds to teleport instantaneously before everyone could react, using his newfound ability to strike at their vital points.

Shimazaki's one-sided assault has finally put the entire group out of action except for Teru, who has proven to be much stronger than Shimazaki had thought when he hit his vital points like the others. Expressing his own surprise to his new power, he comments how it is too late to regret it now and closed in on Teru. However, his Mind's Eye caught the immense power of Mob, who is slowly walking to their location.

Getting excited by sensing an esper with immense power, Shimazaki laughs as prepares himself to intercept Mob once he is within his teleportation range. However, Shimazaki was casually approached by Arataka Reigen, who luckily and unwittingly exploited the Mind Eye's weakness at 'seeing' only espers now. Reigen then proceeds to soundly thrash Shimazaki while shouting out his 'Justifiable Self-Defence Rush' move.

With Mob's arrival, Teru's group recovering, and Shimazaki's own severe injuries and his misassumption of the 'club' mentioned by Mob as a part of a larger organization on their side, the Ultimate 5 member immediately surrender. Reigen remarked at how easily the esper gave up and thought he was into taking over the world. Shimazaki brushed it off by stating that his boss is the only one who was serious about it, and he himself only joined Claw for the fun of it.

Mob got angry at Shimazaki's carefree reason for joining Claw's cause, and immediately scolded him for making a choice that caused much trouble for everyone only because he just wants to have fun. Feeling intimidated both by Mob's anger and his immense powers, Shimazaki immediately escaped via teleportation before anyone could react. The entire group worries that he will come after them again, but Teru remarked that Shimazaki's confrontation with Mob's anger is enough to traumatize him for the rest of his life, and hope that will be enough to make him change his ways for good.

Powers & Abilities
Shimazaki is a remarkably powerful esper, believing himself to be the strongest esper in the world, second only to the boss of Claw. He has shown himself to be far stronger than most opponents with his basic esper abilities alone, such as when he nonchalantly took the punch of Higashio's rubble golem without moving or taking any damage. However, despite his fearsome psychic powers, Shimazaki's fighting movements are too simple, something which Teruki Hanazawa took advantage of by predicting his attacks. Shimazaki is one of the few people who can use two psychic abilities simultaneously.

 * (Shimazaki's thoughts after being beaten by Arataka Reigen) "Grandmaster...? The opposing team has still got a leader of this calibre. I didn't think it was possible for an esper to disguise himself as weak as an insect or a bug... I took too much punches without my barrier. What should I do....Retreat? But..."
