Tacchan

Tacchan (たっちゃん, Tatchan) is a popular kid and childhood bully of Garou. He is responsible for Garou's villainous and negative attitude toward heroes in his adulthood.

Appearance
His only appearance is shown as a black and shadowy figure, similar to everyone else in Garou's flashbacks.

Personality
A typical bully and popular kid, Tacchan always picks on social outcast in his class with Garou as his frequent victim. Despite his reputation of being a bully, he is in fact cowardly since he relies on the number of his friends to take on others who tries to stand up to him as shown when he asked two of his friends to restrain Garou.

He is also shown to be popular enough to make teachers favor him to the point of making them blind about the severity of Tacchan's actions. Tacchan proved to be a heartless person who cruelly enjoyed the suffering of others he inflicted on, and would use those of a lower social status to avoid the consequences.

History
Garou was a classmate of Tacchan. They often played games of hero where Garou would always play the monster and Tacchan the hero. Eventually, Garou became sick of his forced monster role and challenged Tacchan to a fight. If Garou won he would leave him alone. Garou was held down by Tacchan's friends and victimized.

The bullying led to Garou's philosophy where all heroes are in it for themselves and as long as the majority favors the hero, then justice is what they decide. As Garou believes that, he has taken on the role of a monster to fight this biased justice. Ultimately, it has also led Garou to hold an image of an ideal hero of someone who can save everyone.
