I've found him again! This is definitely destiny. He didn't seem to recognise who I was but he recognised Kumagorou, which I still have, and not going to give back until he at least remembers my name! >_<''
I didn't get to tie him up and take him home though :( there were waaaay too many cops patroling around that kiddies park. Like c'mon, would any crimes be committed at kiddies parks? ^_^
