Greetings,

I'm just double checking that your post is referencing that you only roleplay in (PM's) private messaging. Since I think there may be a bit of a typo there. 

A super sentai or power rangers RP, sounds like it could be interesting. Have to say out of the options that's on top of the list. 
I could otherwise be convinced into an isekai (or isekai like), or some form of space-crew roleplay if its some form of bounty hunting, merc, or otherwise adventerous type of work (probably some exceptions). 

Although I am curious if you have any particular limit or restrictions when it comes to roleplay characters, or partners.
