You are a detective investigating the apparent murder of Hiro Mikoshiba, a student teacher at Seiryo High School. Your first suspect was a woman named Yui Mamiya, a former classmate of Mikoshiba. After a long and surprisingly civil interrogation, Yui looks at you and gives a smile.

"Will that be all, then? I have to go pick up my son from school. I hope you can find what you're looking for." she says to you.
