Asteria's Curse Ring. (Patreon)

It is a ring that makes the wearer of Asteria's ring into an Asteria form.

ROLAND's face did not change due to the [Curse Avoidance Collar] he wore around his neck, but it was only a matter of time.

And the collar's protection is gone, and ROLAND has become Asteria completely.

It seems that ROLAND's heart has become a bit like hers too.
