Tsukumo? :3 I'd say Gareki is mine as well.
Ah. I feel the same on the Tokiya, although Syo has been my favourite since the first season and Tokiya's voice is hng-ish due to Mamoru Miyano voicing him.The opening and ending are as sparkly as ever.
I thought so for Nai's :P
I knew about Yogi's because Fushimi Saruhiko, Kida Masaomi, Tamaki Suoh and Light Yagami are also voiced by the same seiyuu.
