Description
Matsuri Tendô, a 16-year-old member of Team Summer B in the 7 Seeds project, hails from a farming family. Disliking agricultural work intensely, she ran away from home before her cryogenic preservation. The specifics of her recruitment remain unclear.

Physically petite, she possesses light brown, bushy, curly hair and large, brightly shining eyes, creating a distinctive look. She consistently dresses in a stylish manner.

Her personality is vibrant, cheerful, and outgoing, often contrasting with her more reserved teammates. Fellow member Hotaru affectionately termed her a "dreaming yumeko-san," noting her determined pursuit of desires during the Minor Heat arc. To better fit in, Matsuri sometimes adopts a shallow maiden persona, though this strategy caused her past pain. Overcoming these difficulties, she actively strives for self-discovery. Romantically inclined, she actively dreams of finding true love in the new world and develops a specific interest in Ryou, the emotionally reserved member of Team Summer A.

Matsuri adapts readily and skillfully reads social situations, enabling quick integration with new people. While advantageous, this social flexibility also contributed to her past hardships, experiences that ultimately strengthened her resolve.

Following Team Summer B's awakening, her courage and determination emerged. When teammates became trapped and immobilized in a hole, she took decisive initiative: providing them water via a makeshift bamboo pipe and embarking on a perilous search for help. This culminated in her swimming through a dark ocean at night, leading to her comrades' rescue.

She played a pivotal role in facilitating contact between Team Summer B and Team Summer A. During tobogganing—one of her hobbies—a dangerous accident occurred. Her cries for help prompted intervention by Ango and Ryou from Team Summer A. Matsuri enthusiastically called them her "handsome princes" and immediately introduced them to her group, bridging the gap between the teams.

Her romantic pursuit of Ryou continues as a developmental thread. Later, aboard the Fuji ghost ship, she deliberately stayed close to him, engaging in conversations that provided him significant food for thought, indicating deeper interaction.

Her name "Matsuri" means "festival," while "Tendô" poetically signifies "heavenly path," often used as a synonym for the sun. Her hobbies include dressing up, applying makeup, and tobogganing.
