Firstly, I have to say, Kingsguard is one of the few if not the only visual novel that I know where I'm as heavily engrossed with its story and characters, Koshiro is my favorite personally. His backstory is really interesting to me, I feel I can relate to him, emotionally and mentally speaking even with differing circumstances. I genuinely just want all the good things for this poor boy.
Secondly, I just thought you should know, in Koshiro's(shocker) route the CG art is a little off, the style is amazing, however his manhood looks fake or unfinished(assuming that's the actualy case). It's not major, but it stood out to me amongst the rest of the incredibly detailed art.
