His suit is accompanied by a neon green ascot and undershirt.

Charlie Morningstar
From what has been revealed, Seviathan used to date Charlie during her younger years, as seen in a portrait of the two of them during what appears to be a high school prom. However, they ended up breaking things off for yet unknown reasons.

Helsa von Eldritch
Helsa is Seviathan's sister. According to Faustisse, the two have a neutral sibling relationship. While Helsa and Seviathan don't hate each other, they also don't particularly appreciate each other and are busy with their own activities. It is unknown if Charlie and Seviathan's romance affected his sibling relationship with Helsa, given her apparent antagonistic relationship with Charlie.

Trivia

 * Seviathan's name is a reference to Leviathan, a creature that takes the form of a sea serpent in the Hebrew Bible in the Book of Job, with "S" replacing the "L". Leviathan is also known as the Prince of the Envy Ring in Demonology.
