Even though one of the Pixiv tags referred to Lyrical Nanoha, I couldn't place these characters based on what I saw. If someone can make sense of it, please correct the tags.

Artist's comments:

聖王教会のシャッハとカリムです。イベント用色紙に描こうと描き始めたのですが、未遂に…。ぐっすんおよよ。

Pixiv tags:

*カリム 　
*シャッハ 　
*リリカルなのは 　
*教会 　
*聖王 　
*魔法少女

That's Carim Gracia and Schach Nouera from StrikerS. Carim has a tendency to do this kind of thing a lot.

Thanks! That was fast.Her intent is obvious, but it's not sexual. see forum #33281.

It doesn't need to be. It can about to be forced to do something, about to get beat down, anything along those lines.

More accurately, "Tag appropriate when someone in an image has a psychotic facial or other expression making them look like they'd be about to commit the deed...", and she definitely looks excited, so yeah.

Carim-sama, do you need a helpful hand catching sister Schach?

I'll take that as a yes *chases after Schach*

Its cosplay time, there was one comic I remember where Hayate was refering to Carim as her teacher of things cosplay.

Now THAT really surprise me.Look at Carim's gentle look.Who would have thought that such gentle-looking girl is so energetic in some ways.And I thought she is what she looks like,like post #456967.

It's always the ones you least expect.
