Its a bit ambiguous what is "demographic overlap". Last pass, we have 3 JRPG chracters, the three of them "anime boys" (Joker, Hero and Byleth), both from titles release in the last 3 years, from IP that had +30 years of history.
Ryu Hayabusa can be label as a "retro character", while Dante can be labeled as a "Playstation character".
Ha! That gave me a good laugh, if those 3 would have great relationship with Nintendo, we would have seen Resident Evil 7/2R/3R, any internal U4 Namco-Bandai game (Tekken 7, Soul Calibur 6, Ace Combat 7, Code Vein, Tales of Arise, ect) or any Yakuza title on Switch.
