Leeza Sei left CLAMP to find her own style and yes, she certainly did that with her third installment of incorruptible cops against the yakuza series.

COMBINATION 1-2 left the readers with something of an amiable departure when the pair of detectives salvaged what's left of their careers after a failed bout against the yakuza....and it should have been left there. C3's story's a messy attempt at another cop story and it might have been forgivable if Sei's penmanship had not strayed so far from her CLAMP days.
