Hatsune Elissu

"I will give you the exit key, But before that... Let's play a game senpai! Maybe I won't kill you!"

- Elissu offering the exit key to Akira in Normal/Hard Extreme Yangire Mode.

Hatsune Elissu is a secondary antagonist who appears as an enemy in Extreme Yangire mode in Saiko no Sutoka as a secret character. The developer of the game confirmed that she is a childhood close friend of Saiko-chan.

Appearance
Elissu shares a similar appearance to Saiko-chan. She wears a similar bunny girl outfit that Saiko-chan wears during Yangire Mode in the game. The only exceptions is that her hairstyle and face are slightly different from Bunny Saiko. Unlike her, which seems to have messy short hair, the latter appears having neat short hair and a single side-swept bang on her left side.

Personality
Nothing is known about Elissu, though she seems to behave similarly to Saiko-chan in Yangire mode, as she also hunts down Senpai and attempts to kill him.
