Final Weapon

The first version of the final weapon is purchaseable through the weapon shop in Kateyou once you reach a Level Rank of IV or higher. To get the Final Weapon to +, ++, or +++ would depend on whether you got Hikari to like you or not. If you are in friendly status you can get the + and ++ with some alchemy items. If you are in the crush status you can get the +++ and even the diamond weapon.
