guys i forgot what a link is... can somebody pls explain to me? help（/TДT)/

Basically it is a bond of vamp and human. Vamp feeds on link human blood while the link becomes an immortal human so the vamp can feed on it forever.

ohhhh, thank you so much! I started reading a long time ago so every time the term appeared I was lost but at the same too lazy to read the old chapters again to read the explanation ╮(￣▽￣)╭

Same time too*
