Dragon Quest Heroes?

Just wondering where the Dragon Quest Heroes games are? They are Mousou games, developed by Omega Force. As well as Persona 5 S is going to be coming to the Switch and is also a Mousou game. But there is no preview information for this.

If your question is asking why the two Dragon Quest Heroes games aren't part of the Musou franchise page... I have no idea. But you can add it to the wiki and wait for wiki moderation.

I'm not sure what you mean by preview information for Persona 5 Scramble but there aren't a ton of preview coverage here other than some unfinished videos, some press conferences, and the deluge of trailers of E3.
