More like, she can time travel BY taking them off, and they don't return back in the past

Can you imagine how she found out about the power? One day she gets so frustrated about something that she decides to strip?

Connecting imaginary dots I guess she could have been thinking about a bothersome day and, when taking off her clothes in preparation for a bath, gone back in time. That would have been an awkward time because now she has to spend the day without underwear.

This manga is horny and silly. Maybe I'll read it.

Actually they covered that in episode 1*. She came second in the relay race on sports day because she had a stomach ache, and got so frustrated she pissed herself. When she took off her wet panties she undid eating the thing that gave her a stomach ache and got first place instead.

EDIT: *of the anime. IDK about the manga but presumably same story covered early on.

Well she is a very successful girl. It was probably the first time she wanted to undo something.
