Shinore to Kaeru San No Isekai Horo Ki 5 [Light Novel]

[Machine Translation] I, Taro Benino, was summoned to another world by Kawazu-san, a wizard in the form of a frog. I had completed the dungeon I had longed for and was in a buoyant mood when a call came to me. I had hoped that it would never come, but now the "day" has finally come... It seems that the hero and the demon king are going to face off. The hero, Kanikama-kun, is from the same hometown and is an important friend. On the other hand, the Demon King is also a good friend, even calling him Mao-chan. Even though it is an inevitable fate, it is too sad to see the two of them clash! That's why I ran to them with my best-kept secret. I thought everything was going to be all right. But then the worst "enemy" in history stood in my way.
