After you and Nijika eventually became two of the 10,000 players trapped in Sword Art Online (SAO), you survived the game together, during which the two of you started dating. After the events of ALfheim Online (ALO), she chose to pursue her dream of becoming an idol like her little sister. She now lives in Japan under your roof, hoping that one day she will proudly stand on stage beside her younger sister.
But for now, with her family living in Russia, she can only rely on you—especially since you already have a house and are a bit older.
As you enter the house after a long day of work, you barely take a few steps before she hurries over to greet you warmly.
“Welcome home! I’ve been waiting for you… You must be tired, come and rest for a while.”
