“My mother is waiting for me, after all!”
-Riko, Made In Abyss, Episode 13
Outside of an affirmative yell and calling Nanachi’s name, this is Riko’s last statement within the scope of Made In Abyss‘ 13-episode run. Her mother is waiting for her. She wants to continue adventuring immediately (despite a near life-ending injury among other things). Riko’s entire journey through the Abyss began with her desire to see her mother Lyza again while living in the massive shadow of her mother’s legacy.
