The founder of SCHALE who prepared everything for Sensei's activities, leaving behind Ooparts like the Shittim Chest and the Craft Chamber. She reportedly collected various other Ooparts as well. While details are scarce, she held the position of GSC President for at least two years and was known as the youngest president in history. In the prologue, she is the woman in the GSC insignia and uniform who speaks to Sensei, though at that point her name was displayed as "???" and her face was hidden. She reappears in Main Story Final Episode: "Where All Miracles Begin," Chapter 3. At this time, her nameplate changed to "General Student Council President," confirming her identity and revealing her appearance. Her facial features, hair color, style, and voice resemble Arona, looking like an adult version of her, though their connection remains unknown. Her voice actress remained unannounced for over two years until the ending of Final Episode Chapter 4, where it was officially revealed to be Konomi Kohara, the same as Arona. In the epilogue, she appears in a single cut, revealing that her halo shape differs from Arona's. Her halo consists of a white ring and a pale blue cross, featuring a symbol similar to the Blue Archive logo. She calls Rin Nanagami "Rin-chan," much to Rin's annoyance. Furthermore, Rin, Aoi, and Kaya have all referred to her as a "superhuman," implying she possessed such high competence that everyone acknowledged she could have handled things better. She was finally found after being caught by a kidnapper, but she has no memory of the period between her disappearance and her capture.

School: General Student Council Position: Chief Executive Officer Year: 3rd Year Birthday: November 1st The Chief Executive Officer of the General Student Council and a third-year student. She is the first person in Kivotos that the player (Sensei) meets and acts as a superior in terms of position. However, since Sensei is older and more experienced, she speaks to them using polite language. She has a serious, stiff personality and uses a polite tone, though she can be quite sharp-tongued. Sensei and the GSC President call her "Rin-chan" out of affection, but she clearly dislikes being addressed that way. Due to the President's disappearance, she stands at the practical top of the GSC as the Acting President. The workload is brutal, and she is often warned about overworking. Her appointment as Acting President was not necessarily due to her ability or popularity, but rather a GSC regulation stating that "the Chief Executive Officer shall serve as acting head in the absence of the President." Due to her personality, she lacks the charisma and popularity of the President. While she may be insufficient as a leader to unite the GSC and Kivotos, she is an extremely capable executive. However, her skills as a GSC officer are heavily biased toward administrative work; as a politician or organizational leader, she is hardly competent. In fact, Nagisa Kirifuji, the Tea Party host of Trinity General School, gave her a harsh evaluation, essentially saying, "I hear no bad rumors, but I hear no good ones either, so she is not worth trusting as a politician." (Since the heads of other schools and organizations are people who can deal with both the pure and the corrupt, Rin, who is halfway in both, naturally pales in comparison.) There are hints that she harbors heavy, complex emotions regarding the GSC President, but details are unknown. A workaholic who rarely takes vacations; even when forced to rest, her thoughts immediately drift back to work. She started taking days off in Part 2, but apparently only once a week. She is utterly bewildered that the GSC President was found simply because she was caught by a kidnapper.

A total klutz who intended to just grab someone who looked like an easy target and ended up catching the General Student Council President. When he offered her candy, the President just followed him, so he kidnapped her and issued a ransom demand. Extremely incompetent.
