eous (zenless zone zero)
The Bangboo in Zenless Zone Zero operated by Phaethon (Wise and Belle). It is used to guide the Hollow Raiders through the Hollows, thus it is the most likely to be out and about.
It wears an orange bandana around its neck with the number "01" printed on it.
Belle and Wise own at least two other Bangboo identical in appearance to Eous except for the number on the bandana: Bangboo 18 and Bangboo 6. However, since Eous is the one most commonly seen, if the number isn't visible or not drawn at all, it's fine to use this tag.
