High-Rise Invasion, known in Japan as Tenkuu Shinpan, follows Yuri Honjo, a high school student who suddenly finds herself on the roof of a skyscraper. She is in a world made only of tall buildings linked by bridges, with no way to reach the ground, where masked figures hunt the people trapped there. Yuri's goal is to escape and find her older brother Rika, who is caught in the same place. The cast splits between survivors who band together, the masks who follow mysterious orders, and a few people able to command certain masks. This page covers 13 characters from the anime: Yuri and her allies, Rika's group, other survivors and the first opponents she runs into, described as they appear in the story, without spoilers.
Protagonist
Yuri Honjo 本城 遊理
Japanese voice: Haruka Shiraishi
The protagonist. A 16-year-old student who wakes up on top of a building in this world of skyscrapers with no idea how she got there. She is terrified at first but soon realises she has to fight back to survive, and starts carrying a handgun. Her focus is finding her brother Rika and a way out, while learning the rules of the place quickly.
Main characters
Mayuko Nise 二瀬 真由子
Japanese voice: Shiki Aoki
Mayuko Nise, a small, wary 16-year-old who fights with a combat knife. At their first meeting she threatens Yuri, but the two call a truce and start working together. She is cold and practical, prefers to handle everything alone and only gradually learns to trust her partner.
Sniper Mask スナイパー仮面
Japanese voice: Yūichirō Umehara
One of the masks, armed with a sniper rifle. Unlike the others, he starts protecting Yuri and Mayuko instead of attacking them after his mask cracks and he regains part of his own awareness. He has a connection to Rika that the series leaves open. He is one of the fans' favourite characters.
Rika Honjo 本城 理火
Rika's group · Japanese voice: Junya Enoki
Rika Honjo, Yuri's older brother and a third-year high school student. He is also trapped in the world of buildings and is already leading a small group of survivors when Yuri reaches him by phone. Calm and strategic, he advises his sister from a distance and fights with a large hammer.
Kuon Shinzaki 新崎 九遠
Japanese voice: Akira Sekine
Kuon Shinzaki, a calm and very polite 16-year-old girl whom Yuri meets later in the series. Her composure stands out in a place where everyone else is panicking, and she treats people kindly. Her role in the story becomes clearer gradually, so the details stay out of this page.
Supporting characters
Kazuma Aohara 青原 和馬
Japanese voice: Kōji Yusa
Kazuma Aohara, a surgeon in his twenties who runs a base in a building topped by a large satellite dish. Intelligent and cold, he has his own plans to understand and master the rules of the high-rise world. He relies on the mask Ain as a bodyguard and offers shelter to anyone he finds useful.
Ain アイン
Japanese voice: Chika Anzai
Ain, a small masked girl who fights with a katana and serves Kazuma Aohara. She is fast, precise and dangerous at close range. Like other masks bound to a person, she follows the orders of whoever commands her, which makes her an important piece in Aohara's plans.
Sachio Tanabe 田辺 幸雄
Japanese voice: Haruo Ogino
Sachio Tanabe, a hot-tempered and stubborn man of around 60 who fights with a spear. He leads his own group of survivors and refuses to take orders from anyone. His explosive temper creates friction with other survivors, but he brings life experience and plenty of fight.
Shinji Okihara 沖原 真司
Rika's group · Japanese voice: Megumi Ogata
Shinji Okihara, a timid boy who wears a helmet and leans heavily on Rika. Despite his fear, he is very good with firearms, which makes him useful to the group. He represents the ordinary survivors who try to stay alive by staying close to braver people.
Kohei Yamanami 山波 康平
Rika's group · Japanese voice: Shin Furukawa
Kohei Yamanami, a young man wrapped in bandages who acts as strategist for Rika's group and carries a gun. Observant and quiet, he helps Rika plan the group's moves between buildings. His appearance is striking, but he is one of the most rational members of the team.
Rikuya Yoshida 吉田 陸矢
Japanese voice: Shoya Chiba
Rikuya Yoshida, a small, idealistic 16-year-old boy who wants to use his abilities for good. He seeks out Rika's group to help them and is accompanied by a monk-like mask that obeys him. His sense of justice pulls him into risky situations more than once.
Antagonists
Mamoru Aikawa 相川 守
Japanese voice: Jun Fukuyama
Mamoru Aikawa, a high school teacher in his mid-twenties who commands a large group of masks. Polite on the surface, he has his own ideas about what to do with the power he has found in this world. With so many masks at his command, he becomes one of the biggest threats to Yuri and her allies.
Yayoi Kusakabe 日下部 弥生
Aikawa's masks · Japanese voice: Yōko Hikasa
Yayoi Kusakabe, a police-themed mask who serves Aikawa. Self-centred and cruel, she enjoys showing her power over others and commands masks of her own. She is one of the opponents viewers find most unpleasant, because of how she treats anyone who crosses her path. She operates as part of Aikawa's forces.
