My Sister Took My Orc

My sister and I chose our orcs at the same time.

She quickly took the purebred, noble, and calm mystical beast, leaving me with the wild spirit snake, whose lineage was mixed and temperament fierce.

Unexpectedly, when the mystical beast advanced, it turned on its master, leaving my sister's appearance ruined and her powers depleted.

Meanwhile, the spirit snake transformed into a true dragon, ascending to a god-like creature, bringing me endless glory.

I went to visit my sister; she had lost her mind, and her inner power imploded, taking me with her.
