Sensei

Sensei is a humanoid, bipedal cat-like being whose vocabulary in everyday situations is limited to a single utterance, requiring Ginko Kuroi to act as interpreter. Despite how brief each remark appears, the actual volume of meaning conveyed is surprisingly substantial. As the sole combat-capable member of the Kigurumi clan within the Nebula organization, Sensei aligns with the "Black Chaos Moderate Faction." To demonstrate that the Sirians—who once committed the crime of invading Planet Riel—still hold the potential to become an "Evolution Species of Love," he chose to take Sōya Kuroi under his protection. Through psychic combination with Sōya, the two merge into a compact giant bearing feline features and fluorescent-colored components, referred to by Grand Paladin forces as the "Nebula Soldier." The combination sequence is notably peculiar: Sensei positions himself behind Sōya, opens his jaws wide to swallow him whole, performs a forward roll, and then completes the transformation while landing on one knee. In a dream Sōya experienced while unconscious, Sensei was depicted speaking in fluent, ordinary language, engaging in a fierce debate with a prominent Seal Faction figure addressed as "Your Excellency" over the proper treatment of humanity.
