Hes not my favorite megaten protag, but I think naoki from majin 2 is EASILY the most underrated in the series
I think him not being drawn by kaneko like the majin 1 guy was gives him a perception debuff to most people but I really like his design. The big coat over the jacket gives him a really bulky impression/silhouette, and I like majin 2's COMPS that look sorta like pagers and are worn on the breast (you can see the same thing on Karen)
He also not silent and I think his easily agitated kinda aggressive personality helps him stand out amongst protags. I'd say I'd want him to get into DX2 so he can get a model but I imagine that because hes neither drawn by kaneko or even a main series character at all pretty much nixes the chances of it ever happening
Him and tokyo tower witch are in my "most wanted, but never ever ever" club...
