A character from Koha-Ace, an alter version of Okita Souji. Originally known as "Majin Saber" during the manga's XP run, she was a Saber-class gag character lampooning the concept of powerful fusions and dark persona (Alter forms in Fate universe), being a fusion of Oda Nobunaga and Okita Souji. In Fate/Grand Order, she appears as an Alter Ego-class Servant, and is a version of Okita Souji who became a Counter Force guardian, similarly to Archer.
The second kanji in her name as "Majin Saber" doesn't actually exist, with "jin" (asset #39621318) consisting of the character for god (神) above the character for person (人).
