It's not really a rebrand though. The ship thing is an idea she got hooked on and talked about day-dreaming being a Vtuber manager and designing this as one of the slots in the company. My guess is that the she liked it so much she ended up adopting it for herself since nobody would, of course making it more appropriate with her current persona. She spent time thinking up the names and designs, so of course she wants people to like them and engage with them, even though the old ones are still as good as they were, and it's what her current persona is built on. She doesn't want to get rid of them or change anything, but she still wants people to engage with her new persona and roleplay like she was a different character, but still her.
(that's why she called it self-indulging, it's what she wants, not what makes sense)
