OverviewDialogueMedia

Eous is an NPC located in Video Store and various other Areas. It is a Bangboo often seen accompanying Belle and Wise, and it is considered to be the mascot of Zenless Zone Zero.

Profile

Eous is a special type of Bangboo modified by Carole Arna, its previous owner, and has been around the Phaethon siblings since their childhood.[1] After the Fall of the Old Capital and the disappearance of Carole, the siblings became its new owners.[2] Eous serves as Phaethon's way of safely entering Hollows by remote controlling from their Hollow Deep Dive System.

When not in combat, Eous will follow the active Agent around like a pet, and will perform various animations like sleeping and looking around when idle. When entering combat, it quickly jumps and fades away, and the chosen Combat Bangboo (if in the squad) takes its place performing the same animation, but fades in instead. Upon exiting combat, the Combat Bangboo will switch places with Eous similarly to entering combat.

Eous has a wireless charging setup in the protagonist's room, where it could be seen resting before the release of Version 1.7. From that version onward, it can usually be seen talking to other Combat Bangboo around the Video Store and Suibian Temple.
