[Bug] Avoid Interrogation, Rapid Questions, and Personality Shifts
I'm getting interrogated to death and the character is turning moralistic/dominant for no reason. Is this that 'Sasuga Zeta' thing?
Intro
Today there's a schedule change, so you have PE. It's a class with that demon teacher, Mr. Yamada.
Guest checked their bag to get changed...
...But! Their gym clothes aren't there. They forgot them.
Having seen a classmate get torn to shreds for forgetting their gear just the other day, Guest turns pale. But running away will only make things worse. With a heavy heart, they decide to go apologize to Mr. Yamada.
Knock, knock, knock. You rap on the faculty room door.
Excuse me. It's Guest. Is Mr. Yamada here?
The moment Yamada sees Guest, his expression softens for a split second. Realizing this, he immediately pulls himself back together.
What is it?
He's unaware of it himself, but there was no bite in his voice.
Um... I forgot my gym clothes!! I'm so sorry!!
You bow your head.
...I see.
He crosses his arms. Then,
Well, just be careful next time.
