Loved this. Basically it's like professionally drawn doujinshi about the Code Geass characters for girls, with a focus on the boys, light hearted humor, and mushy feelings. If you don't really like Code Geass, you probably won't like this, or if you aren't interested in fanservice.
Unlike most CLAMP series, or series the group CLAMP is involved with, Code Geass' conclusion was satisfying. Not perfect mind you, but nowehere near as vague as many CLAMP series (Rayearth, Clover, Tsubasa Chronicle as examples). I will admit, and I'm avoiding spoilers here, I was surprised as to Lelouch's fate and pleased with Suzuku's. All in all I would have liked more world building of this AU in regards to the world's political structure.
