I'm actually surprised to hear / see a new catchable Kin in the game! So the name of the Kin is "Creme Creme" and you can catch this Kin at the lake in the last stage. Of course as always in order to catch one you gotta grind a little. So good luck!
Oh ps. This Kin was made to celebrate the 15th year anniversary of Gaia.
Update: Here is the stats for a Creme Creme at level 50 ~
99 Stamina, 1500 Life, 99 Magic, 99 Damage, 85% Resist, and 40% Accuracy.
So there you go, sadly so far this Kin is nothing but a tank, the accuracy is SO low that during battles the Kin will more that likely have trouble hitting the target enemy. Also the damage and magic isn't so great either, so all in all its sorta pointless in battle but good for collectors.
