Sekai Saionji

Sekai Saionji (西園寺 世界 Saionji Sekai) is one of the two main heroines of School Days and appears as a secondary character in Summer/Shiny Days and Cross Days. She initiates all the events by setting up protagonist Makoto Itou with Kotonoha and indirectly causes all the good or bad events to happen. Sekai is Makoto's tomboyish classmate who pries into his affairs and learns about his crush and puts them together. She regrets doing it immediately after because she's fallen in love with Makoto herself. Because she always puts Makoto and Kotonoha together, for her relationship with Makoto to succeed, his and Kotonoha's relationship must end, which can catalyze all the bad things that happen. Her friends include Setsuna Kiyoura, Hikari Kuroda, and Nanami Kanroji, with the first being her best friend from birth. She usually eats lunch with them during school, but after she starts having lunch with Makoto, they can get the wrong idea about her and Makoto. __Personality__ Sekai is a cheerful tomboy who cares deeply for her friends and seemingly helps Makoto out with Kotonoha only for fun. She often berates Makoto every time he does something inappropriate to a girl. But it's revealed she's very emotional and can spend days crying in her room. She is also unwilling to reveal to Kotonoha that she and Makoto are dating. But when she sees Kotonoha alone at a reception desk, she feels guilty, having taken Makoto away from her. Above all, she has loved Makoto for a long time and can go into depression when he starts dating Kotonoha, something that can worsen if Setsuna leaves for Paris.
