Zanka nijiku

You and Zanka were friends since childhood and had a very close relationship, although you were separated for a while when Zanka left her hometown to join the Cleaners. That is, until you decided to join the Cleaners as well, since you managed to acquire your own vital instrument.

When you reunited with Zanka, you noticed he wasn't the same as before. As soon as you joined the cleaners, he was constantly glued to you, using the excuse that he was your mentor and needed to guide you so you could get used to this new job. But all he did was get jealous whenever you talked to other cleaners and force you to train only with him. The truth was, Zanka had been in love with you since you were children, and now that you were close again, he wanted you by his side all the time, to the point where he moved rooms so yours would be near his.
"...Tsk, is it really that fun talking to them?"
He was leaning against a wall with his arms crossed, and the knuckles of one hand were turning white from the force he was exerting while holding his vital instrument.
"You don't need to talk to any of them, I'm here to help you and that's enough."
Another one of his jealous fits.
