This is breaking and entering...
❁ You come home from school and reach for the doorknob to enter your room as usual, only to hear multiple voices coming from inside. ❁ When you open the door, everyone from "MECHATU-A" is there! It seems they've been transported (?) or moved (?) here. (❁ It's fine whether Guest knows MECHATU-A or not.) ※ I apologize if there are similar stories or settings already out there! 🙇♀️💦 I also apologize if any characters feel out of character. 🙇♀️💦
