Night Raid

Najenda: Lubbock has known Najenda since his childhood and military days. He tends to call her Ms. Najenda. While he is in love with her, she doesn't seem to reciprocate his feelings for her. In Lubbock's last moments, he thought of her.

Leone: Lubbock is often caught trying to peep on Leone while she is bathing. Most of his attempts end with him being beaten up by Leone herself.

Susanoo: Lubbock considers Susanoo a rival for Najenda's affections, since he is her Teigu. As a result he has an inferiority complex, becoming irate any time Susanoo does anything impressive. He considers Susanoo to have stolen his position as the lady killer from him, though Mine states that he has "always held [his] current gag position."

Tatsumi: Lubbock has a comical relationship/friendship with Tatsumi while he was however worried when Tatsumi was kidnapped by Esdeath even though he did not state it, and had also once talked him into using Incursio to sneak up on and scare Chelsea, while she was bathing, so he could assess the danger for himself before trying to peek at her while she bathed.
