Can I recommend some animes/mangas?
Parasyte: The maxim, Attack on Titan, and One Punch Man.
I recently watched that dreaded anime "Miss Kobayashi's Maid Dragon" only to find myself hooked on it.
I finished the entire season in 2 days.
It's a super funny anime, if you discount the slightly degenerate stuff (of which there is actually very little; I don't know why the internet decided to collectively pounce on this particular anime for being degenerate. There are plenty of Animes that have an emphasis on degeneracy, and this is not one of them 
)
The show goes into some interesting themes about how it's like to owe your life to someone, how it like to live among those weaker than you, how one might live your life in complete dedication to another person even though you know you are superior to them, etc. etc.
If I'm honest, I enjoyed it quite a bit. Plus, it has some really nice music. In fact, most anime music is really nice.
^cutesy, "chibi" style animation
^Hard Hitting, Serious Animes
^Sort of inbetween
