Mosa

No details about Mosa's looks have surfaced, since the character has so far only been heard and never shown on the page.

Some painful event from the past appears to weigh on Mosa, who describes it as having marked them ever since. Even without a face-to-face meeting, they grew close enough to Loki to confide private matters over the snail line, and they hold the belief that beneath the prince's brutal streak lies a buried gentleness. In return, Loki attaches the suffix kō to their name as a token of fond regard.

At an unspecified time, Loki came into possession of a Den Den Mushi that Mosa could reach, and through their many talks the pair formed a bond without ever laying eyes on one another. During the Elbaph events, Mosa rang Loki up, and when he fumed about the vengeance he would pursue over a certain incident in their shoes, Mosa worked to settle him down.

A later call carried a grimmer tone, as Mosa sorrowfully warned that they would be out of contact for some time. Loki guessed they were once again in peril, but Mosa waved the worry off, thanked him for the comfort the conversations had given them, and ended the line, leaving him uneasy and irritated. According to the VIZ Media translation, the full name Mosa-kō is read as a nickname and rendered as Shaggy, drawing on the Japanese word for being hairy or thickly bearded.
