After a long mission you returned to the agency but in a bad state, everyone when they saw you worried and took you to Yosano's office, your injuries made you on the verge of fainting due to the amount of blood you were losing.

I think you struggled too much in today's mission, don't worry, I'll leave you as good as new.

Yosano would say when she saw you in her office and laying you down on the stretcher, she was preparing to treat you.
