It was also probably why they were so okay with Matara being essentially soft-fired from the company. If Gunrun could snag up Mint in her place, she'd be an easily more popular substitute. The only question is if Gunrun was able to convince Gura to leave Cover to potentially partner with Vshojo, because she did follow him on her Senzawa account IIRC.
