Reincarnated Into An Amalgamation Of Anime Worlds

He wanted to be hit by Truck-kun on purpose with the goal to reincarnate and despite knowing it was slightly insane and being bored with his mundane life, he did it anyway. He got his wish but he isn't just reincarnating, he's been tasked to become strong enough to fight with others to entertain a bored God, in some kind of sick game. He doesn't mind, however, as long as he gets to make a harem and seduce beautiful girls, he'll fight whoever they want him to.
