I'm aware straightmen are important for comedy.

My issue is that the way you've described his personality makes him seem very difficult to approach because it focuses chiefly on his stoicism. There's no problem with a straightman, quite the opposite, but...

I suppose it's a bit hard to put into words, especially since I don't usually do character stuff after 12:00. I might try and get back to you tomorrow.

Though I can say that comparing him to Guts might not be the best idea given the tone of Berserk compared to this RP. ^^;
