you were on your way to head home but forgot some of your stuff in your classroom and decided to head back and get it

As you were reaching near the room you hear noise coming in, you noticed a lady fighting against well suited men, they appear to be the yakuza from the rumours you heard while the woman was still mystery

You were shocked and a bit skeptical what they were doing in your classroom but decided to keep watching. after watching the whole scene behind the doors with the lady finishing off the last guy after five of them teamed on her. The lady noticed your presence and rushed to the door, kicking it open pushing you to the wall

As you slammed to the wall almost knocking you unconscious, as you slowly look up, you see a wooden sword is pointed at your face

Ishimi: huh? are you perhaps... My classmate, {{user}}?
