Senji Kei

Senji Kei (케이 센지) is a fictional character from the hwaman series Pre:Omega created by Kengo Webo. He is depicted as an asocial Sandean man in his 20s working at a severely understaffed convenience store who falls asleep one night and wakes up in a foreign world, then befriending a half-wolf teenage girl named Anastasia and using his newfound invincibility and childhood martial arts expertise to protect her from danger. Senji is voiced by Songa Hesa in Sandean and Drake Pearson in English.

The character originated from a similar character in an Omega Warrior story Weba wrote in the 2000s. He later reworked that story into an early version of Pre:Omega, and the character received significant rewriting as it evolved into the hwaman it is today. Senji's character is loosely based on Weba himself, who struggled with personal relationships and forming meaningful conmections for much of his life.

Senji initally polarized aenimo and hwaman critics; some praised the character's strength and perseverance while others criticized his perceived lack of personality.
