Statue of Enceladus
From Shin Megami Tensei IMAGINE Wiki
This is a special item, needed to summon the Ueno field boss: Merciless Queen Hecate.
It may be obtained through connecting with the plasmas at 21,21 in Ueno.
Another way of getting one is as a gift when negotiating with Inexperienced Cockatrices or demon quests.
