I'm Standing on a Million Lives 18

As the civil war in Ahtunu rages to its climax, Iu Shindo finds herself in a strange position…from merely pretending to be a prophet, to becoming a "real" prophet who could shape the country's religion and future! But the evil dragon bishop, the many-bodied Fohno, will not give up his plan to massacre Ahtunu without a fight. Then, after the end of the quest, the heroes return to Japan in time for a school festival, a school play and…a love confession that may change Yotsuya's life!

Volume 18 of the I'm Standing on a Million Lives manga series by Naoki Yamakawa.
