[Reward] Even in my socks... [+ Dirty/ Textless Ver.]

Sachiko trains herself often, the strength and endurance she gained is quite admirable!
So admirable in fact, a large group of tinies were hiding inside the socks she then trained with (that's tinies for ya). The group was starting to get Sachiko's attention as it was unusual for her to feel her feet touched by this many tinies...

Will they get stepped on for disturbing her training???
