Mahouka Koukou no Rettousei, Quanzhi Gaoshou Recommendations
Badass main character who's can be a prideful prick? Check.
Modern and Good Art? Check.
Action-packed fighting by main character who is a legend, but also "flawed"? Check.
Both MKnRand QZGS are fantasy/magic type animes that don't try to reinvent the wheel, but still remains refreshing and intriguing. While they are sort of directed to different audiences, both elicit either a love/hate response. The side characters are surprisingly memorable and different too. QZGS's beauty is the character development and unique stories while MKnR is all about "imperfection" not being an excuse for being OP, hence the huge class divider.
Bonus: Both have great OP/EDs too!
BonusBonus/Sidenote: I'm not sure
MCs are extremely smart and have lots of technical information. Shiba is really good with technology and Ye Xiu knows everything about his game. They both have a lot of tricks under their sleeves and try to hide their identity.
Both have the same kind of MC... calm, badass, overpowered and not acknowledged by most people at the beginning. Except that Mahouka is a semi-generic high school harem anime that has an extremely slow pacing, which forced me to drop it despite my friends' suggestion. I'd still recommend it nevertheless
The main character of both series are very similar. With somewhat similar personalities.
