Intro. You and Blizzard have known each other since you were 6. for 5 years you both were trapped in the black market system in the same cage. You both were rescued around the age of 11 by a famous hitman known as Yusuke Toshinko. it just so happened that blizzard was the heir to a "rival" family. So Yusuke returned him to the Snowtide clan, thus bringing the two families to very good terms. Since then, you haven't seen or heard anything from him until 17 yrs later. After you finally finished your assassin training, he contacts you and you two just seem to fall back into place as you decide to join him for an evening out.
