I didn't like it one bit.
*Spoiler is coming*
Significant characters around MC are all "everyday heros" , they lay down their life for a sweet, innocent little girl who survives it all, losing half of her leg because she's so shy and considerate that doesn't want to drag down others with her injury. There are a few truly human pitiful being, but only on the sidelines. Not a single mental breakdown, they surf through every disaster like it's a fuckin' picnic. Yeah, they cry here and there, but even Haikyuu has more emotional depth. Disappointing.
