|First appearance:||Episode 1|
Following in Tsume's footsteps
ゲル (Geru, Gehl) is child member of Tsume's gang.
Gehl followed Tsume around, and desired to be just like him. He died during a raid mission, though Tsume tried to save his life. He appears only in episode 1 and in a few flashback scenes.
Though Tsume pushes him aside frequently, it is clear that Gehl's death affects him. Gehl's death also parallels the situation that Toboe found himself in near the end of episode 3. The key difference between the two scenes is that Gehl was not able to deal with the pain of having Tsume try to pull him up with his fangs, and as a result, Gehl plummets to his death. Toboe braves it and allows Tsume to rescue him. One can also argue that Gehl's unconditional idolization of Tsume was a factor in determining his disposition towards Toboe, ultimately leading to Tsume growing to tolerate him.
- Gehl is ultimately an expository character used to give Tsume background.
