Chillin' in Another World with Level 2 Super Cheat Powers (Manga) Vol. 11

Flio finds himself in a bind when a trio of djinn from the Dark World capture him! Until, that is, he turns the tables by claiming their powerful magic for his own, saving the last surviving wyvern of the mountains in the process. The wyvern then entrusts Flio with the Second Heart - which may be the key to making Flio's sweet dreams come true. Meanwhile, the djinns' master. Valentine, is in a bind of her own. She's trapped, without a glimmer of magic left! Can Flio and company rescue her before it's too late, and more importantly, should they?!
