Eba

Eba serves as the president of the track and field club at Asahiyama High School, easily recognized by her tanned complexion and long high ponytail. Possessing a sharp eye for athletic talent, she sets her sights on Yotsuba early on and relentlessly pursues her recruitment, going so far as to organize a training camp on the eve of final exams. She skillfully exploits Yotsuba's inability to turn people down, using it as leverage to get her way. Notably, Eba stands among the rare few who can see through the quintuplets' identity swaps. Her unyielding and aggressive approach becomes a pivotal trigger in the 'Seven Goodbyes' arc, sparking conflict between Yotsuba and her sisters and ultimately driving their emotional growth.
