Good Kid? Bad Kid? Makai Gate

Synopsis

The messiah Wataru is turned into a "bad kid" by an enemy character. Bad-kid Wataru's wicked expression is something to behold. His deliberate moves to shorten his friends' lives keep you on edge. The way his evil heart returns to normal through Himiko's simple little charm is also delightful. There's even a scene where the Nio Brothers sing a parody of "Mothra's Song."
