Bishounenized desecration of Alice's Adventures in Wonderland: The gap moe shota twins boogaloo
This manga is pretty much as you would expect: if you're for some reason a fan of the franchise, you'll probably like it to at least some extent. If you're fan of the genres, you might also like it. But if you've just picked it up randomly without being interested in any of those, you're not going to have a nice read. And I don't mean that in the "you need to read the main story to understand" way.
The story is... basically non-existent. Most of the content is various insignificant happenings which
mostly consist of "Alice interacts with her harem". There's not much connections between the scenes except for the characters. You understand what is happening, but you don't understand why it's happening. And not in the original Alice in Wonderland way. Just in the good old "no writing skill" way. Third of the volume doesn't even have anything to do with the "main" story at all and is just unrelated in-universe short stories. The only significant thing that happens is a character trying to show off their trickery by giving Alice a "riddle" that all sixth graders and up would know the answer to. Kinda laughable, but probably not in the way the author intended. Inventing own riddle would be preferable, but at least don't use one of the most overused ones if you're going to copy.
The characters are, expectedly, not exactly characterized and all of the named male cast is ultimately just "lovingly teases Alice". That's their character. I say "named cast", because any male character who doesn't have a crush on Alice is just a nameless background character. That's how much this franchise is dedicated to make the protagonist a harem lead. Also, the only other female character beyond the protagonist somehow looks more like a cross-dresser the way she's drawn.
The art is typical shoujo-style with the focus on characters and from simple to non-existent backgrounds. But well, it's not exactly bad, especially considering the genres.
Bloody Twins isn't good manga, but then again, only a fool would expect anything of substance from a reverse harem, genre that is synonymous with sub-tier quality most of the time. But at least it's a short manga.
