Huh.
Natsu Kagura's scenario is credited to a

. So I assume he's the writer.
Kenji was also the writer for Kagura Douchuuki, among other things. Looking at his VNDB entry, it looks like he was with Studio e.go! since 1999, jumped ship to Debonosu to do Kagura Douchuuki and its spin-off visual novel with the school, left in 2009 to work with Tinkerbell, came back in 2012 to do Kurenai Kagura, in 2013-14 did a few games for Devil-Seal, and then quit the field (last post on his PIXIV is 2014). But yeah, this guy wrote Natsu Kagura, Oni Kagura, Ama Kagura (the shooter), and Tsuki Kagura. Ah, okay. Looks like he left the h-game industry behind and is now writing mainstream light novels. I feel like I've heard of Everyday Magicians? His twitter handle is hoshinewone. Edit: I have to be mistaking it something else, there's no way I'd heard of

" (twitter handle S_maru). Which is obviously a psuedonym, but now that I know to look for it he's been working with Debonosu for a while; they were writer on the 2nd Kagura mystery dungeon game, Kagura Gensoutan. Char also wrote Reimeiki 15 (Hatsuka) & 17 (Keika). Okay, Char's career started back in 2004 and they've done work for numerous companies, including ANIM, Black Rainbow, CLOCK UP and Liquid. He's been a regular for Debonosu ever since Reimeiki 2 (Yukari's first appearance in that series). A giant chunk of the Reimeiki and post-Reimeiki games are written by Char. Not a majority but a large minority.
So yes, you
are right and it's a completely different writer.
