Mob Shisai Dakedo, Kono Sekai ga Otome Game dato Kizuita node Heroine wo Ikusei Shimasu

An unfortunate heroine appeared before me. It seems that this world is an otome game, and I am just an unnamed mob priest who appears briefly in the early stages. I could fulfill my role as a mob and quickly exit the game, but wait a minute, if things go on like this, the heroine is going to face terrible hardships. To save this cute and kind yet unfortunate heroine, I have no choice but to train her myself!
