Story (10/10): The story is quite solid, the arcs didn't feel rush. The manga in 6 volumes manage to capture, develop and close each arc appropriately.
I started Ohana Holoholo because the story seemed different, and that caught my attention. "Adult yuri" (I'm not saying "adult" as "hentai") is something that stands out in the normal yuri pattern... but man, how wrong I was. Ohana Holoholo is more that yuri, it has many great elements beyond the relationship between the female protagonists.
The principal topic is family, especially this particular family of 3 adults and a child. Their story (told with serious and funny moments) will keep
you with them until the end.
Art (8/10): It's not a "moe-style" manga, but in my opinion the art is lovely. It fits the story and gives you a heartwarming feeling. The scenarios are detailed.
Character (9/10): As I said, the thing that attracted me, it's that the characters are adults. An as adults (and as a family) they are not perfect.
Maybe you can hate them sometimes (Michiru... Maya...), based on the decisions they make, but they are well written, and just like life itself, each one of those decisions makes them grow.
Although I love Yuuta's precious eyes, I feel that sometimes it's almost a perfect child. Do not get me wrong, Yuuta also grows (as a character) in the story, I only say that in comparison to how childrens could be, Yuuta is overall pretty nice (and not too realistic).
Enjoyment (10/10): Even, if you're not a yuri (or yaoi) fan, I can assure you that you will like this manga. I'll tell you this again, more than romantic love, it's a story about family love. It's beautiful!
In the future I will read it again... for sure!
