Hanamora is quite suggestive and often flirts with people regardless of gender. he's similar to yamada from the previous game in this regard. hanamora enjoys incorporating english words into his speech and insists on being called super high school level chef instead of super high school level cook, giving off an urban vibe. despite this, he is generally friendly and upbeat when not making suggestive comments or hitting on someone. hanamora takes great pride in his cooking and becomes upset when it's suggested that his dish contains a laxative during the first trial. when monokuma appears with the monomechas, hanamora frequently denies that things are actually happening and dismisses them.
It is implied during the despair arc that Teruteru is bisexual.
Hanamura is the killer in Chapter 1. After he found out Komaedas plan to kill someone in the party, Teruteru tried his best to kill Komaeda during the blackout, but instead, accidentally killed Togami. Teruteru himself believed in the Monokumas theory more than anyone, and wanted to get out to see his mother again.
