Alpha is the sole male Humaritt and final creation of Dr. Ren, identified by an unknown serial number and a childlike physical appearance featuring mint green hair and green eyes. He remained preserved in nutrient fluid for an extended duration due to Dr. Ren's inability to activate him. Alpha's unexpected awakening occurs through contact with the female Humaritt Lila, who triggers his release from stasis.

Upon awakening, Alpha displays extreme timidity akin to a frightened child, avoiding others while instinctively seeking comfort and protection exclusively from Lila. This profound dependence activates a maternal instinct within Lila, fundamentally reshaping her emotional development and catalyzing her journey toward independent thought and self-determination.

Alpha's presence and reliance directly drive Lila's pivotal evolution, culminating in her choice to prioritize caring for him over sustaining her partnership with Najica. This decision signifies Lila's complete transition into autonomy, with Alpha symbolizing a new beginning as they depart together at the series' conclusion.
