Wataru and Sakuya would actually make a very decent manzai
pair, with Isumi and Saki being the triggers for our boke Wataru.
I... have a thing for Ayumu as well. (No not like that) She's one of the more normal people on the show, and she adds her own "normal" flavor in a show where you've got rich people, talking tigers, superpowered butlers, maids, an exorcist, and a Student Council President
armed with a wooden Masamune.
Also, there's that perverted priest Linn. The fact that he's voiced by Junichi Suwabe
and that he invokes a parody of Fate/stay night
using Hayate makes him awesome too. That, and playing Isumi's Dojikko
moment over and over again.
