All these are pretty different manga stories, with similar drawing, in the Kagesaki's style.
I'm a scanlator from Brazil, translating them all (except Strange Mansion, but in the future, maybe...) to portuguese.
Oniichan is an AAS project, so maybe somebody here knows it. But and the other, does anyone know them and liked it?

i like chibi vampire but i dont have the chance to read the manga but i watch the anime..
her arts is really cute.

actually, the anime itself don't have Kagesaki's art style, but it does resemble her art style a little.

In my opinion, Karin/Chibi Vampire is the best of all, but it's more because there's not much of the others translated to english (only 2 chapters of Hekikai no AION and Oniichan Control, 10 on Sakura no Ichiban, and 3 or 4 of Strange Mansion I think...)

I want to buy the american version of Chibi Vampire, but as I live in Brazil, it will cost me around $400...
As I don't have that amount of money for the moment, it will have to wait a little....

Last I checked we were doing Oniichan Control, but I haven't seen anything for it in quite some time. Will have to ask the higher-ups about what's going on with that.

yeah. the chapter 3 have already been realeased in japan, but the scan of it didn't appear yet. I'm just waiting it to start the cleaning, and then take AAS translation, and retranlate it to portuguese...

Or if the staff agree, I would like to do the editing thing on Oniichan since I'm doing it myself here...but the staff would have to agree with it... I don't mind to be the typesetter or other... As you can see, my english is good, even though I'm novice on translating...
