Optics are important so they let her in and Lui just helped to make it 5 so there could be a center for dance numbers. Just look at the group song for Lui's 3d and see how well it works to showcase 1 member at a time with the others flagging evenly to the left and right.
It's also why Kiara was very 'Nerissa, you're a sub for the group' when she joined, dispite Nerissa being the biggest Kiara clit-licker in Hololive. If they would have been at 4 when she joined, Kiara would have rushed to have her officially join the group to balance it out.
