No knowledge of the series or game is needed. It's basically set in a slightly more advanced version of Japan, which is connected to Alternate Realities, inhabited by non-Humans. The card game has "Buddy Rares" which are basically a ticket to the Human world for lucky non-Humans. The price is that they become a Buddy for a Human (Note, they can ditch the Human at will, most just don't).

Can either take place in the Human world, or a fantasy world. I don't mind either. The why for why you don't need prior knowledge of the series, is because I won't be including card games. Most card game rp's boil down to a dice roll of cards if the players are fair, or just l337 hacks. So, this rp is more slice of life, which will evolve from that if the player wishes.

- Similar to the above, except there's no forced link. Two worlds have gateways that allow travel between dimensions for any purpose someone wants. Eg, Vacations, work, etc.

- Humans open a gateway, a team heads in to investigate and then things go from there.

- More idea's inbound, including whatever idea's you wish to suggest.

Buddy Monster x Human
Human x Friend's Buddy Monster (triangle pairing)
Father x Son/Daughter (both are monsters)
Brother x Sister/Brother (both are monsters)
And whatever else you wish
