In what is definitely in my top 3 favorite isekai mangas, Yankee Wa Isekai De Seirei Ni Aisaremasu is an adorable, fun, and unique little isekai. Yes there are cliches (Truck-sama, girls falling for the MC, cheats) but it's really fun because this isn't your normal protaganist-
No, it's a delinquent who favors an 'iron pipe' as his main weapon and couldn't care less if you were a peasant or a king- if you wanna go, bring it, punk. ORA! Lol.
While it does have its weaknesses (I literally hate every female character in this) it has an underlying, mysterious plot that keeps me hooked. Plus, chibi spirits. How can you hate that?
