WN/Guy Crimson/Relationships

Velzard
Velzado is Guy's first subordinate as they formed a pact with each other. However, they're more akin to partners rather than master-servant relationship since they addressed each other casually.

Rudra Nam Ul Nasca
Guy and Rudra have been at war with each other in their own war game, with Guy leading the demons and Rudra leading the humans. Both are obsessed with defeating the other though Guy's degree of obsession is lesser compared to Rudra's. Guy considers Rudra's to be his best friend.

Leon Cromwell
To Guy, Leon is a trustworthy friend, and he has become quite familiar with his personality.

Milim Nava
Guy fought her to a stand still when both ascended into True Demon Lords. After her rampage was stopped, along with Ramiris, they became acquainted with each other. Guy respects Milim to some degrees.

Rimuru Tempest
Guy was initially interested in him due to him becoming the first True Demon Lord within hundred of years and acquiring an Ultimate Skill. During the Walpurgis Banquet, Guy became even more amused with Rimuru due to the display of his power and personality. When Rimuru evolved his subordinates into True Demon Lords, sensing the ascension of several Demon Lords, Guy immediately departed to Tempest to confirm whether or not Rimuru was his enemy. After the conversation and listening to Rimuru's explanation, they both became casual towards each other again.

Ramiris
Acquainted since ancient time after stopping Milim's rampage, Guy seems to be very close to Ramiris, going as far as to tell Leon if he killed her, he would become his enemy.
