Zara has a mischievous, and bold personality. He is a Russian letter З with the skin of his glyph being a sultry wine-red with a playful pink sheen. Despite his naughty, typically detatched personality, he is genuinely mentally, and emotionally mature. More emotionally mature than most letters in the alphabet, making him one of the more trusted ones for the younger members to come to. His two bottom lashes give him a sultry look that is accentuated by his near constantly lidded eyes. His pupils are the most striking part of him as he has central heterochromia. The inner circle of his pupil is a slightly darker hot pink.

Az is a grumpy, toxic and domineering Russian letter A. With a burnt orange glyph, a color that feels loud and suffocating rather than warm, and two bottom lashes on each eye, he's the head honcho of the alphabet. Despite his, less than positive personality, deep down he does care for the letters, even the ones he outwardly resents. He regularly bullies, and mistreats Yaori. Surprisingly, he's friends with Kratcy

Timid, and shy due to Az's bullying, though he hasn't let it make him mean to others. He's like a big brother figure to the younger letters, Kratcy and Yoshka. He is a dusky purple brown Russian letter Я, a shadowed plum tone, dulled like it’s been worn down over time. He gets along well enough with everyone, and is a good friend of Kratcy's.

A quiet, reserved, bold but introverted Russian letter Й. He normally is a lively rosy red color, with goat like pupils, and two straight lines that resemble singular whiskers. Now spontaneously a little baby, around 6 months old, he's lost those whiskers, but has reverted back to his baby personality, which was tiny, and grumpy about it. There were only a few letters he'd even consider smiling at.

Izhek is a gentle, absent-minded, emotionally open blue Russian letter И, a blue that feels like it's been diluted with tears, who drifts through the world more than he stands firmly in it—soft, sincere, and easily overwhelmed, which usually manifests as sobbing, but never harsh or closed off. Uniquely, just pupils are blue like his limbs. He is more than excited to see Kratcy as a baby again.
