Say to Tiana in SS: Calm down. ...

That's why she is called the white devil.

Naiye is called a tyrant because of the characteristics of her magic gun party: making friends with guns.

Anyone who tried to resist her was bombarded without exception, and then bowed down to her and wanted to be a member of her harem, so it was circulated that "anyone who was bombarded by Naino will become lifelong friends" and "one of the introductory ceremonies of the Takamachi family is to eat Naino's SLB"

Naiye shelled out the vast harem (and his daughter and son-in-law, .........................................).

This is the origin of the title of tyrant.
