I'm going to be direct about this one, because it is disgusting in every possible way.
There is 3 girls from the main 6 that is not annoying asf in this manga, which is Julia, Yamada and Kaoru... i mean Kaoru is not a slut and loves mc (but she is his sister), Julia doesnt really care what these tards doing plus doesnt talk too much, and Yamada (best girl) really loves mc and have a cute personality... Ayano is the purest rubbish among fictional characters, boring and disgusting personality, with an even more disgusting past and with even more disgusting and repulsive attitudes.
I particularly found the protagonist interesting, compared to all the other trash that appears. And if we compare it to other harem/ecchi protagonists, he is without a doubt a good MC. He is direct and truthful with his feelings and satisfies all of the girls' fetishes... I feel bad for him, because he likes Ayano throughout most of the manga. He is hardworking and very focused on his activities.
I will emphasize how disgusting FMC is (or what appeared to be the FMC), but it isn't. Ayano; Ayano is disgusting, repulsive, annoying to an extreme that makes you want to simply stop existing... at first she is acceptable, a typical FMC harem character, but as time goes by she becomes every bad adjective that can be given to a fictional character. And somewhere around chapter 38 or 39 proves everything I'm saying (don't read).
Characters that I would like to have more space are certainly Julia, she has more volume than Ayano, she is prettier, she doesn't talk much... and to be honest, she is very honest with her feelings, just like the MC. And the icing on the cake, she is much more talented than everyone else, considering that in addition to volleyball, she is a monster at basketball. And unfortunately it only served to satisfy yet another horrifying fetish of the author, which is... hair?!
I could give more details about Yamada and Kaoru, but I'll be very brief. They are two of the 3 best female characters in my opinion, their personalities are less irritating... Kaoru gets upset a lot, but she doesn't hold a candle to the others, we have to consider that she plays the role of the protagonist's sister too. Yamada is kind, beautiful, hardworking, talented and captain of the volleyball team, in my opinion the best female character.
There is no story, they are all volleyball players and the MC is the coach, but we don't see even 5% of volleyball in the story (which I think is good in ecch stories) since the focus is not a solid, well-constructed story.
The art is good and to be honest, it was the strongest point that made me continue reading through these long and painful 74 chapters. For ecchi art, it's one of the best I've ever seen, to be honest.
If you're looking to keep your sanity away from exaggerated fetishes, disgusting characters and a sloppy story. Stay away from this work! I'm telling you, it's not an ecchi where you'll see useful things... it's almost a serialized fetish hent4i.
I have real mental problems having stayed this far. It had signs of a good ecchi with an acceptable story, but it turned out that most of the characters are deplorable and only serve to cover the author's strange fetishes. There are 3 characters that throughout the work managed not to make me vomit in general terms, Kaoru, Yamada and Julia. The rest is deplorable, low, repulsive and... idk, its just bad.
*My rating wasn't just 1 or 0 because there were some characters that I liked and felt sorry for being there, and the art is beautiful.
