I'm glad I'm not the only one who liked the, often looked down at, "power of family/friends"! Author did a good job with the short flashback to show us what she was lacking, the insecurities and self doubt every young person is going through, not to mention someone who's expected to carry a heavy burden! We often tend to forget many of the shounen characters are barley teens! It wasn't drag out and we had a nice character growth!
My only "issue" is how the mc and even other, supposed heroes or fighters look too damn scrawny! What's the problem of putting some meat on those bones?
