Somehow I find myself running 4 at the moment. Mesutchi and Osutchi, a Japanese V1 P2 (I have the secret character Sekitoritchi atm), and a P's. Mesutchi and Osutchi I'm running long-term since I want to learn more about their breeding, the P2 I started because I wanted to see if getting the secret character works the same as it does in P1 (it does), and the P's was because I couldn't resist and really wanted to play a color Tama haha.
I'll probably drop back down to just Mesu/Osu at some point since it's a bit much.
