Kou returns to Japan after a few years overseas to attend school and reunite with his older sister Kaoruko and osananajimi Ena. They are overjoyed that he is back together with them. Little did he know that they are quite well-known at school: Kaoruko as the Jeanne d’Arc Scientist and Ena as the Emerald-Eyed Witch. There’s a huge commotion now with him around and the student council leader Sayaka declares that she will disband any club that doesn’t have anything to show by the end of the month. This puts Kaoruko’s science club and Ena’s astrology club in danger. Of course, they come and ask Kou to help them!

CG Artist: Riv

update: removed dupe images

You have a thin line running across the top of all of your pictures.
Might wanna fix that.

Edit: either try downloading the file you got, or if you have the game re-screen_cap it.

Base +5, Zero Angel +28, Arkoth +7

Thanks, gonna fix them soon.

edit: Even the lossless BMP file I got, they still have that thin lines like JPG version. I have no idea how to fix it now.
edit2: I tried to re-download it again but it's no use and I don't have the game either. Let's hope someone else might rip the another set of CG from this game. If I found the better version, I would surely upload it. For now, I'm very sorry.

Base +22, Zero Angel +28

This would've been a good CG set if it weren't for that distracting line.

Here's to hoping that a new set will be released soon without it.

Base +22

The sister is the black haired one.
