Nenji (ネンジ, Nenji) is a student of Musashi Ariadust Academy, belonging to Class 3-Plum. He is simply described as a "slime with around 3 HP" and is noted for trying to act brave and chivalrous only to get squashed under someone's foot.
Abilities:
High Tolerance to Injury
Although he has little to no defense to keep himself from being crushed by others, he is seemingly immortal, able to return to his normal shape when he "loses his hit points".
Shapeshifting
Nenji can allow himself to change shape into anything he wishes; he once used his ability to turn into a hand and, while connected to Nate's Argenteés Chaînes, grabs Toori and Horizon to safety.
