Sorry, no patterns, but they're all the basic body pattern from Sayjai so they shouldn't be very hard to figure out if you really want one xP (body pattern link: http://kandjdolls.blogspot.com/2011/09/amigurumi-free-basic-body-crochet.html)

Note: Rin's body pattern is obviously not the same, but it's easy to improvise. It might be possible to take Sayjai's body pattern and simply half the numbers.
Note: His shirt was made with very thin white yarn, which is why his arms look a little weird. xD Use regular white yarn and you'll be good to go~! (I'd suggest making his shirt longer too, by crocheting more rows on the "backloops" Round)

Lost my original photo (R.I.P. Windows Vista...) so I took the one from my deviantart, which is why there's a watermark. xP

This is actually my own personal pattern. I want to add some more detail to him (i.e. the paws) before I post the pattern. =)
