Isekai de Zenra Yuusha to Yobanaide
異世界で全裸勇者と呼ばないで
A woman named Runa Hatagami is transported to another world while bathing in a hot spring, arriving as a hero wrapped only in a towel. She discovers she has no clothing and is given a strange "Hot Spring" ability along with strong defensive power. Though she manages to summon a bath towel using her skill, she remains nearly naked. A witch, who is attempting to bring back the Demon King, places a curse on her. As a result, Runa is unable to return to her original world.
