Summary Summoned to Another World... Again! from Zinmanga X
Summoned to Another World... Again! summary: Once upon a time, a man was summoned to a different realm where he became a hero and saved the world. However, his fame caused him to fall into the typical isekai trope. Unfortunately, he fell into a "trap" and was unexpectedly sent back to his original world. To make matters worse, he was reincarnated as a baby and had to start from scratch. The tale follows the formerly heroic and overly-imaginative fellow who is now a moody high schooler. Unforeseeably, he is called back to the other world in a surprising twist of events.
