Yu Sugino (#8059)

[Revoc]

Probably credited as Hiroshi Sugino here. Not by coincidence, 裕 could be read as Hiroshi.

[CHz]

Probably.

I'll also take a swing that the "Haruori Morita" on that album is Kaori Morita, based on the similarity of ka (香) and haru (春), but obviously that one's much more of a guess.

I finally found the Tenchu 3 credits on Nico Nico Douga.

Though, it's an annoying horizontal scrolling and is a bit difficult to read. =/
I think our suspicions are correct (especially Yu Sugino). What do you think?

[CHz]

Yeah, that's definitely Yu Sugino.

I'm less sure about Morita, because that really looks more like 春 than 香 to me, but if the game has a typo then that might be why the album also has a typo.

Nice! I've linked Kaori Morita too. 森田春織 doesn't show up in Google and she performed with Gen Ittetsu on a bunch of albums.
