Yankee-kun Isekai Tensei!?

Invincible Yankee Aomi Yuu was gravely injured in a fight with an opposing team and lost his life... or so it seemed. When he woke up, he was in another world?! Showing up out of nowhere, Yuu ended up being captured by the arrogant, handsome prince Iswald. Yuu thought he was going to get killed and managed to escape narrowly, but it was Iswald, the one who captured him, that saved Yuu's life when his life was truly in danger. For some reason, Iswald wanted Yuu to pretend to be the prince of an enemy country... A boys-love story between a handsome prince and the strongest Yankee from another world!
