Abathur wants to assimilate the Youkai into the Swarm. Gensokyo will instead assimilate the Zerg into itself.

A different take on Gensokyo's Heart. After his death at the hands of Kerrigan, Abathur awakens in Gensokyo as Abathur Yakumo, a female Youkai working for the Gap Hag herself. Her job? Do what she already did for the Swarm, except for Yukari, instead. Collect Essence, spin strands and sequences.
