The relationship between Vulcan and Lisa begins under false pretenses. Lisa initially approaches Vulcan while working undercover for Giovanni, posing as an assistant at Vulcan's Workshop. While living under her real name, she maintains her secret identity as a White Clad operative named "Feeler" who specializes in pyrokinetic combat against the Fire Force.

Lisa's concealed identity as "Feeler" creates a complicated relationship dynamic because her allegiance to Giovanni contradicts her developing feelings for Vulcan. Lisa starts a mission to obtain intelligence and betray Vulcan, yet she ends up forming real feelings for him.

Lisa begins to see things differently after witnessing Vulcan’s strong work ethic, compassion, and morals. As they spend time together, she feels torn between her loyalty to the White Clad Order and her growing feelings for him.

When Vulcan learns her true identity, he responds with kindness instead of anger, believing she’s being controlled by Giovanni and can break free.
