Post an anime guy who's voice is relaxing to hear.

Louis from brothers conflict, he is such a sweetheart with a very soothing voice ^^.

gin, rượu gin Ichimaru (Bleach)

Seiichi Yukimura from Prince of Tennis. Here's the proof. :3

Tsukito Totsuka from Kamigami no Asobi <3

Japan/Kiku Honda(Hetalia) I like his voice, especially when singing. It makes me melt and feel relaxed.

Shirokuma (from Shirokuma cafe)
I don't know, but when bạn say "relaxing" only this guy comes to my mind...
(if that doesn't count) my 2nd choice would be Koushiro from Digimon... but I guess that's because it just isn't his character to freak out.

(yes, I mean the Japanese versions)
