- Not to be confused with Souji Yoshitani
|A teacher that is seduced and scorched.|
|Hair color:||Dark Blue|
|Voiced by:||Derek Smalls|
Yoshitani is seduced by student Yuki Toudou who has sex with him on the roof of the school. She makes him reveal that his father is in possession of the Spear of Longinus. At that moment, a mysterious white robed girl appears above them and magically sets the pair on fire. Yoshitani dies and his body burns to a crisp. His corpse is later brought to the city hospital autopsy room.
Following the incident, police investigators incorrectly conclude that Yoshitani expressed his love to Yuki and, after she supposedly rejected him, he raped her and committed suicide out of guilt by burning himself to death. The school's headmaster and Yuki Toudou's father persuaded the police not to make the incident public.
- Despite his father Souji Yoshitani using Yoshitani's name for a bank safety deposit box, the teacher's first name is never stated in the series.
