A certain reborn Fujimaru Ritsuka sacrificed herself to stop that pink-haired bastard who had blown himself up.
To be safe, after she died, the little rascal even sold herself to Alaya, asking only that Solomon's spirit origin be restored.
I give you everything. I hope you can give them a happy ending.
And so her existence was erased. She became part of Alaya, one of its many laws:
[Everyone loved by Fujimaru Ritsuka will have a happy ending]
As a result, every Heroic Spirit, including a certain Solomon, was reborn after witnessing her death.
The Heroic Spirits: ...Heh. You're quite the troublemaker.
The currently three-year-old, truly tiny Fujimaru Ritsuka: OwO?
More or less, it's a heartwarming little story about a group of reborn Heroic Spirits trying to raise a tiny little girl, only to accidentally turn her into a flirtatious young woman...?
