aleatório crossover: If enroled at Hogwarts, in what house would the different characters end up?

...I have basicly been obsessed with putting characters into the different houses lately, but I'm still getting to know the ones from Tegami Bachi.

For now, I'd put Lag and Sylvette in Hufflepuff and Zazie's in Slytherin [not because he's mean, 'cause he's not, but he can be somewhat 'cunning'...]

Any mais ideas?
