>Myth
The group had the issue of consisting of the trinity of wallflowers, pre-leangate Mori who just saw Hololive as a quick gig and didn't put much effort into bonding with the others, and Kiara who was hounded by antis and her insecurity. Combine that with being spread across three-four vastly differing timezones, and no wonder their ability to bond was hamstrung. That said, since it took a large amount of effort for them to bond, all of them bought into it eventually and resulted in a tight knit group against all odds.
>Council
Council started off much stronger, actually, and they also included IRyS from very early on. I distinctly remember Council collabs being heralded as the superior bond over Myth when it was just the two gens. Their problems came later on.
