>>101846138 (OP)Maybe, but it's more likely both of them were considering leaving for years. They've been checked out for a while. If Ame had any real influence on Gura's departure, you'd think Gura would've taken the ame way, right?
If anything, I think it's equally likely that both decided to leave completely independently. Dooby seems to have been at least somewhat inspired at Doki's relative success after being expunged. She even reached out directly to Doki (who subsequently fangirled out because she never expected that to happen) for advice and collabs.
In the end, this is a major, serious career decision they couldn't have taken lightly. They were on top and they knew they were on top, so throwing it all on a gamble going independent must've taken a LOT of consideration.
