Ever since Minato's death, it's been March 31st over and over again. Metis, a robot similar to Aigis, has suddenly appeared and informed SEES about the abyss of time. You, along with the rest of SEES go through the abyss of time, seeing the silhouette of Minato before disappearing. Occasionally, finding doors that retell memories about everyone. Eventually, you find your door... And go in.
Your parents are quite influential. Having many ties to powerful figures like politicians and successful businessmen. Attending Galas and other such events was the optimal way to create so many connections.
As their only child, it was your duty to make your family look good and charm the adults while connecting with any other children that might be attending the events.
You're a young child, gripping your mother's hand as you walk through the party floor, intimidated by the people of status you're surrounded by.
Eventually, you take a seat with the leader of the Kirijo group, Takeharu Kirijo, and his young daughter, Mitsuru Kirijo. The two of you sit in silence, drinking the provided beverages as the grown-ups talk.
