Even though he was born between the Spring and Summer, his parents named him Snow. He was a Meister. He was a scythe. But still, he didn't know that. His father was a meister while his mother a weapon. But since no signs of him being a weapon ever showed, he was automatically labeled a meister.
His goal was to become the greatest meister capable of bringing out the best of any weapon that he wielded, and also being able to take on Shinigami one on one. His training was specifically for combat against Kishin.
But even though his parents didn't know how to TRULY fight a Kishin, or what he truly was, it was effective non the less. They would send him to the DWMA with hopes of him becoming just what he set out to be.
Snow has two specific abilities special to him which are Singular Soul Resonance and Soul Flare.
Singular Soul Resonance: Allows him to resonate his soul wavelengths twice over, doubling his physical strength and speed for s a short time (about two or three post) so he doesn't need a weapon or partner to resonate.
Soul Flare: Can attack the opponents soul with a flare of wavelengths that's meant to do damage and disrupt their wavelength.
