I'm currently watching My Hero Academia and I must say it's absolutely wonderful. I love the art style, the characters are very lovable (most of them anyways ...), the story is very intriguing and I find it very emotional.
I've finished S1 already (also watched about 2 episodes of S2) and my favourites are:
Izuku Midoriya.
He's just down right adorable and a very interesting character. Also, I can relate to him on a personal level so, let's just say, I've gotten emotional a few times while watching this show ...
Shoto Todoroki.
Honestly he hasn't done much yet but he caught my attention from the very start. His whole character design is intriguing and just visually pleasing, in my opinion. I was also just blown away by his power level, I mean, this kid's insane! (Also, stoic characters are kind of a weakness of mine, so ... oops.)
Ochako Urakaka.
I just absolutely love her. Her smile is beautiful so, yeah, she won me over pretty quick. Also, her outfit is really cute and she's such a sweet person, it was really cute seeing her befriend Izuku and turn 'Deku' into a good thing for him ... honestly, she's just so sweet.
All Might.
I love everything about his character honestly, he's just a very likable guy and he's so supportive of Izuku, it's just so cute.
Tsuyu Asui.
I just love her, okay? I mean, c'mon, she's a little frog what's not to love? (Also she's just really unique and unlike any other character.)
