Master Cyphona:
You are here to ask about the mission again, huh? Go to the Garden of Spirits. Once there, defeat the Kerberos Liger, Kerberos Fort, Kerberos Nero, Fury Sylph Barrena, Fury Sylph Temptress, Fury Sylph Purka, Fury Kerberos Liger, and the Fury Kerberos Nero, and bring back 100 Unstable Spirit's Energy. We'll be using those items for research.
