I thought this was some Super Smash Brothers doujin from the title (SSB+).
It wasn't, obviously, but I'm pleasantly surprised by how much I'm enjoying these slices of sibling life.
I think I kinda like this version better. I’ve read both and seen the anime. This one has more of a plot than the other one. Lol. And the characters have more real feelings mixed in.
I dropped this one because of some reasons:
1. I did not like the vain nature of Chiko & Chika. They are way to unserious and selfish. It hurts to see the other siblings liking them.
2. Despite 1. I could have continued to read arguing that everybody got the right to love who ever they want but the translated version of this manga is too small. I have difficulties to read and because of 1. I do not feel it is worth to strain my eyes trying to read.
