Envy Series

The Envy Series is one of the seven sins and also one of the two sets from the Curse Series claimed by Motoyasu Kitamura.

Overview
After Motoyasu uses Lust Spear IV's Temptation on Naofumi's party, Filo begins to lust for Naofumi, which makes Motoyasu quite jealous. For some reason, it is also a level IV weapon. The spearhead is phallic-shaped. Motoyasu uses said spearhead in an attempt to take Filo's purity. Its special effect, Ressentiment, sets a field with the effect of amplifying feelings of jealousy. There doesn't seem to be a repercussion for this Curse Series. Although Motoyasu sees women as pigs and can't understand their words, it was unlikely caused by the curse.

Trivia

 * It's been implied that the transformed tip of the Legendary Spear while in its transformed form greatly resembles some sort of sex toy from the Modern World.
