Is that the same kid?

Is the boy on alice nine's ohp and cross game the same one from ruri no ame?
Heh, he's cute. Please nobody tell me he's actually hecka old (as in 14-16). xD Let me keep the illusion of somebody's cute little brother~~

And also (rant alert).
I will NOT rescue my little sister should something bad happen to her. Unless I'm told to. By someone I respect. Or fear. Not on my own will.
She is the most horrible in the worst way.
My brother and I are replacing the chair covers (we cover our chairs) and she decides to come over here, while I'm tying the knot in the back, and pull it off. No way. So I hold it back so it won't fall off and I ask her what she's doing. She stares at me. I repeat myself. Stare. My brother comes and tugs it out of her hand by force. She starts screaming.
I like my grandparents. They blamed her. Rightfully.
Then she makes all these comments.
When I return to my room, she's like LEAVE!
She takes my ball that my dad specifically told her not to touch because it's mine. I'm just not going to bother, right? So I go towards her because I have my book on the table (which she's standing next to). She knows its my ball. She knows. She just won't ever admit it. And she tells me NO-NO! Like she has the right to, because it's "her" ball. I swear. If she were my kid... I'd kick her. And send her away to the orphanage.
I like that our hate is mutual. I don't like that I can't screw with her stuff while she can screw with mine.
