Sorahiko Torino

Gran Torino (グラントリノ Gurantorino) is a retired Pro Hero and a former teacher at Yuuei.

Appearance
Gran Torino is an extremely short, elderly man. His hero costume consists of a full body suit along with a cape, a belt with the letter "G" on it, and a dark coloured mask.

Personality
Gran Torino is a very forgetful man, repeatedly asking Izuku what his name was despite being the one who nominated him for work experience training, and failing to remember it even after being told what it was, calling the boy "Toshinori".

Despite his eccentric antics, Gran Torino is an intimidating man, as All Might was terrified over the idea of he once again taking his hero name in order to teach Izuku.

Past
At some point in the past, Gran Torino was part of the Yuuei Staff, All Might's homeroom teacher, and a close friend of his predecessor. During a practical training session with All Might, Gran Torino made All Might spew.

Field Training Arc
In his apartment, Gran Torino is on the floor with what is seemingly blood everywhere. Izuku Midoriya, the person Gran Torino nominated for, enters and is horrified to find the elderly retired Pro Hero on the floor seemingly dead. Gran Torino suddenly gets up, explaining to the boy that he was carrying a plate of sausages with ketchup on them but fell and got ketchup everywhere. Gran Torino asks the boy his name to which Izuku tells him his name. However, Gran Torino does not recall nominating him. He suddenly remembers, calling Izuku "Toshinori" in the process. As Izuku tries to leave the apartment to speak to All Might, Gran Torino asks Izuku to fight him with One For All, saying that he wants to see how well Izuku can handle One For All, wanting him to put his Hero costume on and fight him. Gran Torino once again forgets who Izuku is. Thinking that Gran Torino is playing games with him, Izuku declares to the elderly Hero that he needs to learn how to control his power as soon as possible since All Might is running out of time, telling the elderly Hero that he doesn't have time to be fooling around. Izuku tries to leave, but Gran Torino jumps and leaps in front of Izuku at an incredible speed, stopping Izuku from leaving. Gran Torino tells Izuku that since Izuku has a goal to learn how to control his power, then he has all the more reason to stay. The elderly Hero asks Izuku to use One For All and fight him.

Izuku puts on his Hero costume and faces Gran Torino in a mock battle. Gran Torino's incredible jumping speed allows him to strike Izuku without being countered. Izuku prepares to use One For All and predicts that Gran Torino will attack him from behind. Izuku's prediction turns out to be correct, allowing Izuku to get into position to hit Gran Torino, but Gran Torino pushes Izuku's arm out of the way. The mock battle ends with Gran Torino telling Izuku that he is too rigid and his awareness is disjointed which are some reasons he is unable to use One For All properly. Gran Torino explains that Izuku's main problem is that thinks One For All is special. Izuku asks Gran Torino to explain what he means, but the elderly Hero tells Izuku to figure that out for himself and goes to eat something. Gran Torino is outside and overhears Izuku finding the solution to his problem in controlling One For All. Gran Torino ponders that Izuku's thought process is flexible and commends All Might for finding an excellent successor.

In the morning, Izuku tells Gran Torino that he put what he discovered as practice but found it to be difficult to do so. Gran Torino replies that it is difficult due to just discovering how to use One For All more effectively and comments that All Might in his younger days used One For All like it was normal which is why All Might's way of guidance is wrong. Izuku becomes fascinated from hearing about All Might's younger days, to which Gran Torino replies that he made All Might spew during a practical training session, commenting that All Might could not handle the power emotionally due to being entrusted to it by a late friend. Izuku asks Gran Torino about All Might's predecessor, much to Gran Torino's surprise. Someone arrives with a delivery for Gran Torino and Izuku goes to fetch the delivery. Gran Torino ponders that All Might didn't tell Izuku about his predecessor. The delivery turns out to be a new microwave as Gran Torino broke his old microwave during his mock battle with Izuku. Gran Torino decides to have breakfast, telling Izuku to set up the new microwave. After doing so, Izuku heats up his and Gran Torino's breakfast which is taiyaki. Izuku serves Gran Torino his taiyaki, Gran Torino excitedly takes a bite of his taiyaki but it is frozen. Annoyed, Gran Torino goes to check the microwave, telling Izuku that he didn't put the microwave's plate in properly and as a result didn't turn and only a part of the taiyaki was heated. Gran Torino's comment causes Izuku to realize his next problem with One For All; that he has been using One For All on one body part and not on his whole body. Izuku activates One For All throughout his entire body with Gran Torino being impressed with Izuku's quick learning. Gran Torino asks if Izuku can move while using One For All throughout his body, to which Izuku replies that he is not sure. Gran Torino asks if he can test whether Izuku can move around while using One For All throughout his body. Izuku replies that he can test him.
