It's unmistakably his voice. I think they just keep it a "secret" like how mafumafu is kamiboku's vo./gt. . 

I'd say that's pretty dead-on (-sans the angle.)

I had no idea until I got some Detective Conan-related video in my YT suggestions. Had to do a double-take considering this is already a few months old.

Dug a bit more into the comments. It's theorized that...

-  After オトイロハ (otoiroha) disbanded (which was really just a brief hiatus before their ジグザグ reformation), 長戸大幸 (Mr. Daiko Nagato), founder of the Being Group which produced ZARD & WANDS, scouted him for his "indies-era" voice. So he was familiar w/ his visual kei bands.

-  He went under the pen name 上原大史 (Daishi Uehara) and did some composition/arrangement work for a ZARD tribute album and other works (w/ Being Group.)

-  He performed in 琳派ROCK (Rimpa Rock) (shown at 5:16.) This alludes to the fact that he was already involved w/ the Being Group.

- Became the 3rd vocalist of WANDS. The band suddenly active after 20 years (which makes this all the more special.)

Completely overlooked the intense fan-research that goes into j-idol blogs & wikis. I should know considering I've done the same for some Johnny's -related v-artists. Going to comb over this to fix some details.

** Bonus Fact:

It seems like ジグザグ's channel views grew fivefold with the 真っ赤なLip MV release. Also explains why CD prices have shot up too (something I actually observed a week-or-so ago.)

bruh that's so wild! Good for him getting a gig like this! Although I'm not really into Zigzag anymore, there's no denying he has a great voice, so he truly deserves this! I was just surprised because I vaguely remember seeing a tweet about the day he joined and I didn't realize it was him out of all people!
