Somenki

Although Somenki respects Jucerino, his eagerness tends to miss the mark.

Jucerino gets irritated by his over-enthusiasm, but Somenki remains persistently loyal.

When moving alongside Sumeragi, Somenki encounters Kibitsu Mikoto.

During their clash, he's torn apart and defeated.

However, as long as his mask isn't shattered, he remains immortal.

After being reduced to just a head, Somenki is used by Sumeragi for his own purposes.

Eventually, Jucerino repairs him and restores him to his original form.

Somenki was brought into existence because Sumeragi told Jucerino that if she didn't create a demon who could kill humans, the other demons would dislike her.

Thus, his creation was a political move as much as anything else.

According to both Sumeragi and Moki, Somenki has a strange "tsundere" side that shows up in unexpected ways.

He fumbles between being tough and unexpectedly shy, which only adds to his unique charm.
