Mimori Tougou

Two years ago, Tougou was scouted by the Taisha for another group of Heroes with Nogi Sonoko and Minowa Gin. Because of her strong aptitude, she was adopted by the influential Washio family, giving her the name Washio Sumi. Her real family was compensated with lavish gifts for her services and sacrifices. When fighting the Vertex alongside Sonoko, she activated her Mankai two times, first losing the use of her legs and then losing her memories of the past several months. Afterward, she was returned to her original family, who told her that she had lost her legs and her memories in a traffic accident, and she retook her birth name. The Taisha gave the Tougou family a lavish house next to the Yuuki family, in part for recompense and partly because Yuuna had the highest Hero Aptitude of anybody tested. After this, Tougou began attending Sanshu Middle School and joined the Hero Club. She prefers to be called by her family name.

In the first season, Tougou is a wheelchair-bound girl with long, black hair tied in a low ponytail using a blue ribbon which she drapes over her left shoulder, along with dark green eyes. In the second season, she has fully regained control over her legs and can be seen walking. Compared to the other girls, Tougou grew more maturely for her age, She is noticeably more well-endowed and being the second tallest in the group. Her school uniform is a long-sleeved black cardigan with a red ribbon on the chest area, with a cream-colored shirt beneath and black tights. Her casual wear is a light blue dress that cuts beneath her bust to reveal a white undershirt. Her wheelchair is black and dark blue.

Her Hero uniform is a tight-fitting blue and white bodysuit with detached sleeves, tassels along her waist and feet, along with four long, blue ribbons which trail from her shoulders and serve to prop up Tougou's body as well as move her around. Her hair grows much longer in her Hero form and is flows freely from a white hairband around her ears. Her Mankai gauge resembles a Morning Glory and is located on her left breast, over her heart. In the second season, she forgoes the ribbons and receives a pair of blue and white shoes for her feet.

In her Mankai form, she has a light blue and white long, flowing kimono-like dress and a golden ring above. Her Mankai takes the form of a large flying spaceship mounted with several laser cannons, which Tougou can use to fly around the battlefield.

Tougou is a mature, intelligent girl who is nonetheless always willing to speak her mind. She studies computer programming and runs the Hero Club's website, and is also very good at baking sweets. She is a Japanese history buff and is extremely patriotic, refusing to eat non-Japanese food or use English loanwords in her speech. Tougou is a pessimist by her own admission who will often begin to have dark thoughts when left alone, but she can also be quite silly at times. Tougou prefers to be called by her family name (Tougou) instead of her given name (Mimori), even by her best friend Yuuna.

Tougou fights using a variety of ranged weapons from a long distance. Her first fairy, Aobozu, allows her to use a sniper rifle that lets her fire powerful shots from extremely long range. Her third and second fairies, Gyobudanuki and Shiranui, give her twin shotguns that she wields in reverse grip, and a pistol for midrange, respectively. Her fourth fairy, Kawabotaru, creates portals around her which autonomously fire lasers at nearby threats.

Tougou's Mankai grants her an enormous gunship that can fire multiple cannons at once, not unlike a navy battleship. It can fly to incredible heights and has a self-destruct mechanism.
