Megamaniac67
When an ordinary gamer dies in a freak accident, he awakens in the afterlife with an unusual offer: instead of a random weapon or cheat skill, he's given the legendary Ruyi Jingu Bang-the staff once wielded by the Monkey King himself. Reborn into the absurd world of Konosuba, he's quickly roped into Kazuma's ragtag party alongside Aqua, Megumin, and Darkness.
Armed with a weapon that can change size at will, crush monsters with a flick, and vault him over castle walls, he's ready for adventure... or so he thinks. Between Kazuma's schemes, Aqua's divine disasters, Megumin's explosive tendencies, and Darkness's questionable hobbies, the staff's greatest challenge might not be fighting demons-it's surviving his own allies.
With each quest growing more chaotic, the "Monkey Staff Hero" learns that in this world, power alone won't save you... but a little cunning (and a lot of patience) just might.
Do you want me to also make a shorter, back-cover style blurb for it? That could make it more "fanfic cover ready."
