Formerly "Miko" and "海未だ!" ("Umi da!") on the English Server. I teach engineering in university for a living but my free time pretty much revolves around this game.
I usually accept friend requests in EN at the end of each month. I monitor the activeness of my friends at the end of each month by checking rank growths.
I just cleaned up my received friend requests. If you sent me a request and I didn't respond back then you may - if you are still interested, of course - resend me a request. I will try my best to respond to requests as soon as possible from now on.
