Can you get any more obscure than that?
Probably, considering that...
1) Black Tiger and Zig both managed to dig up the answer (but gave you guys hints instead of revealing it).
2) You yourself recently presented a screen from a game (CD Battle) that has fewer owners and ratings on daisakusen than Kagami.
Just because you and a few other guys here were stumped doesn't make it unfairly obscure. It was a large image from an important scene in a game that, again, is owned by a decent number of people.
