I have watched the first four episodes of this series now and I think this is quite a fine series so far. Of course the premise is quite simple and doesn't look like it will much change during the 13 eps (though I could be wrong), and thus the humour is pretty one-sided, but so far it hasn't been boring at all, though there is repetition (what comedy wouldn't have, anyway). More like it's all the funnier when you can predict a perverted reaction from Yuji every time the situation at all offers a chance for such a thing.

Edit: Goddam... I thought this was a 2007 series, but this was an ancient one... Uhhhuh... My bad.

Necromancy ZAP!
