Hi Makoto! If you're still looking, I highly suggest you check out the FC I'm a part of, Magitek Knights. Everyone's very friendly, very active, and all across the game (from starters to endgame). We just like to have fun, etc. Hit me up later if you like, Eirikr Juchardt or just take a look and try reaching out to someone in the FC if you'd like to know more about what we're about;

Magitek Knights

I personally play in the evenings/nights after 7pm CST (8pm EST), but there's always someone on.
