Kei Sakurai

Оригінальне ім’я: 櫻井螢

The descendant of a bloodline that allied with the Obsidian Round Table during World War II. She joined the Table to fill the spot left by a member who died eleven years prior. Furthermore, as her age - contrary to the other members - does actually match her appearance, she is too young to have met the five highest-ranking members of the Table. (Source: VNDB)
