Well, someone gives it a go if not our main pair without thinking. Anyway, shouldn't they do it soon? The cat angel seems to be a bit in a hurry, it looked like they don't have much time.
In any case, I'm a bit confused, they are middle schoolers? This manga is from 2000, didn't Elle stated she was born in 1982? I don't remember, did they actually mentioned their age? It's frustrating if they keep it so ambiguous.
