It is currently unknown to where Merlin's Seven Deadly Sins Tattoo is located.

Personality
Nothing is known about Merlin's personality yet she shows some childishness as she playfully told her teammates that their supposed meeting with the Great Holy Knight might turn out to be a scolding from their superior after an incident with the Great Druid Altar being destroyed by her team. Merlin is also apologetic as she asked for her captain's forgiveness for knocking him out.

History
Not much of her past, but Merlin joined the Seven Deadly Sins after committing a sin related to her title Boar's Sin of Gluttony.

Ten years ago, Merlin, along with the rest of the Seven Deadly Sins, was summoned to a castle to meet the Great Holy Knight, Zaratras after defeating a troll queen and, at the same time, destroyed the Great Druid Altar. After they found him dead there, all of them were ambushed by the Holy Knights. For some yet unknown reason, Merlin was the one that rendered Meliodas unconscious and apologizing to him before doing so.
