lol i was telling others that Chika was a KageTsukki love child;
I would probably be the hundredth person saying this: 2.43 is more slice of life, working on interpersonal relationships, personal issues/identity than actually honing of volleyball skills and team work, which Haikyuu is. Not that Haikyuu is lacking those and 2.43 does not have the aspects of teamwork etc, its just really really different from Haikyuu.
Like how different Slam Dunk, Kuroko no Basuke, and Ahiru no Sora are.
There are lots of things 2.43 can improve on; its not the best Sports anime nor is it the best Slice of Life. Some characters' personality/identity are not fully developed or explored yet, lots of plot holes, timeskips, questionable decisions and events. For me its not boring buuuuut I'm not really excited to watch it asap when the episode drops.
