I like the IrisXTheo pairing. I hope that's what materializes and moe-character just stays a sister figure.

I'd give this series a higher score if Waldheim became a sister figure, but then later the real sister appeared, having been brainwashed into a stasi killer. The real sister would tell Waldheim not to steal her precious big bro and shoot her dead in a true yandere fashion.
