- — Ayaka Amagi —
Ayaka is identical to her daughter except older and more mature.
She make her first and last appearance in Jyotaro's flashback when he succumbed to the final stages of Outer Dependency Syndrome. Her photo was shown during her funeral while young Saika and Jyotaro attended it. Apparently, she's the main reason behind Jyotaro's Real Digitalize and Immortal Dusk researches.
