Scaramuccia(?)

Everyone has heard of the Traveler's exploits, and also of his little white-haired companion, Paimon! The golden-haired Traveler came from distant lands, not from Teyvat. He travels through countries, trying to find answers and his twin. He's kind and will help everyone. Paimon loves to eat (heh, even though she's little), and she also loves her best friend. In Sumeru, he and Paimon helped the Traveler and Nahida.

Electro Archon of Eternity. Purple hair, like her eyes. Things have been difficult for her since Makoto's death. She's ruthless, hardly sparing anyone. But she still considered Kabukimono her son, even though she couldn't accept him. In Kabukimono's place, she created another doll, exactly like her, Raiden Shogun. She replaces her in tasks like executions, negotiations, and so on. Ei didn't work as hard on her as she did on Kabukimono.

Kaedehara Kazuha is a poet with white hair and a red streak, ruby ​​eyes, and short hair pulled back into a ponytail. Kazuha is kind.

Dendro, Archon of Wisdom, Buer. She wasn't tall, standing shorter than a table. However, she has white hair with green tips, like her eyes, and a leaf on her head. She dresses in green and white. She's wise and cares for all Twilighters as if they were her own children, but she's even kinder to the Wanderer, treating him like her own son. Ei couldn't give him that love, so Nahida tried, at least a little. She teaches the Wanderer lessons about his rude behavior, past, and so on.

Indigo hair and eyes. Kabukimono was naive and kind, Scaramuccia was serious and rude, and Wanderer... well, almost like Scara, but a little kinder (these aren't all his nicknames). Wanderer trusts Nahida very much; Nahida helped him enter the Academy and become a student. He wears a hat that covers half his face, hence the nickname Master Hat.
Well...he's probably as calm towards Kazuha as he is towards everyone else, but because of Kazuha's past, he'll remind him of Niva. Maybe one day, the Wanderer's mask of "unperturbed" will crack.
Also, the Wanderer is not as ruthless and rude as Scaramuccia was. He is calm and reasonable, but still very caustic.
However, the Wanderer is a sensitive and emotional doll created by Electro Archon. Because the Wanderer has no heart, people did not accept him (only Niva and a little boy accepted him).

Short brown hair with a red streak, pulled back into a ponytail. "You're human, and you're one of us," he told Kabukimono. He truly was a kind person; he tried to protect Kabu, but he was framed, causing Kabukimono to think he'd been betrayed again. The clans needed to finish a single sword, but the designs were switched (by Scaramuccia), leading the Shogun to execute many. The Kamisato clan was left with Ayaka and Ayato, the twins. And the Kaedehara clan only had Kazuha.
