Description
Eigo Sawatari is a male student at Ayanagi Academy, standing 170 cm tall with a birthday of November 28 and blood type B. His appearance features dark brown hair parted in the center with bangs and light brownish-yellow eyes. He consistently wears the school uniform properly and dons specific training attire: a white zip hoodie with black trims, a light yellow shirt underneath, white pants, and white dancing shoes.

He possesses strong observational skills and logical thinking, frequently sharing analytical thoughts with peers. Sawatari acts responsibly and maintains respectful relationships across different teams. His character shows a preference for efficient transportation and new experiences, though he self-identifies a lack of humor as a weakness. Rules compliance holds importance for him, and he addresses stress through structured problem-solving.

Sawatari attended Ayanagi Academy's Middle School Division alongside Nayuki Toru, Tsukigami Kaito, and Tatsumi Rui, where they were collectively nicknamed "Princess" (Tatsumi) and "Knight" (Sawatari). His family has served the Tatsumi family as stewards for generations, resulting in a lifelong connection with Tatsumi Rui. Initially intending to join the instrumental department due to violin and piano skills, he switched to the vocal department after learning Tatsumi would be saddened by their separation. During middle school, he participated in the Drama Club and resided in the top class of the Music Department with Ageha, Tatsumi, and Tsukigami.

Key relationships include his childhood friendship with Tatsumi Rui, encompassing shared history as classmates, roommates, and teammates in Team Hiragi. Sawatari frequently assists Tatsumi during illnesses and believes in his potential as a leader. He exchanges greetings with Nayuki Toru but expresses confusion regarding Tsukigami Kaito's placement on Team Otori despite academic standing. Within Team Hiragi, he collaborates with Ugawa Akira, Toraishi Izumi, and Inumine Seishiro.

Musically, Sawatari performs as part of Team Hiragi, contributing to songs such as "The Elegance" (a duet with Tatsumi), "Blue Sky SEASON" (with Nayuki, Tsukigami, and Tatsumi), and "Gift ~Curtain Call~" (with the full cast).

His Sagittarius zodiac sign, nicknames "Saru-kun" (from Ugawa) and "Knight-senpai" (from middle school students), and the use of contact lenses due to poor eyesight are noted. He sleeps on the bottom bunk in shared accommodations, favors vegetables as food, and identifies rainy days as his preferred weather for listening to rainfall at home. His animal motif in Ayanagi-themed series is the monkey, and drama CDs reveal his report cards often note "serious" and "grown-up" as descriptors.
