https://youtu.be/uzbe_Ra0l_I?t=5160Mel's message about Zeta on her final stream.
I'm a bit unsure on how to translate it since i'm just a JSL, so here's a transcription:
>ゼータ。スイパラと脱出にいった!結構IDのなかでに会ってるかも!?また一緒に服みにいったりしょ!ゲームもしようね!たまに毒舌なのがいい!でもメルには優しい!>Zeta. We went to sweets paradise together! I think among the ID members, i've met with you a lot, right!? Let's go shopping together for clothes again! Also let's play some games together too! I like how sharp-tongued you are sometimes! But you are still kind to Mel!
