Seijo to Shite Shoukansareta no ni... Nazo no Shoukansamurai ni Hazukashi Meraretemasu.

Airi is an ordinary high school girl with a slightly strong sense of justice. She's summoned to another world from the bathroom after her club activities! Apparently, she's been chosen as the "Saint," destined to help the hero defeat the Demon King... Before introducing Airi to the hero, the summoner conducts a physical examination, suddenly kissing her and touching her in inappropriate places! "Whatever happens, happens in this world!" she thinks, but then the summoner tells her, "Only you can save the world!" Reluctantly, she tries to accept her role as Saint... but trials and other obstacles delay her departure, and she can't seem to get out of the brick tower where she was summoned!?
