Genshi Otome to Kami no Tou

Synopsis

A colossal structure dwarfing the vast jungle at its feet, built by the Ancient Ones - the Tower of Gods. Legends say within its walls there lie countless relics able to fulfill any wish one could possibly make. But for the wish to be granted the pretender must pass the Trial of the Guardian - a fight with the mysterious ancient monster, lurking wakefully in the shadow of the Tower. Few are those who have faced the beast and lived to tell the tale... The stories that follow are about young girls, brave and desperate enough to confront the dreadful Guardian in a bitter fight for a wish that's worth dying for. (Source: Mangadex)
