After Sakura Mizukami shows up at the Kazama household to ask for a favor, Kenji Kazama and his sister Noe end up unwillingly participating in a footrace at the local shrine. Intent on winning the prize—spring water that only appears once per year—Sakura recruited the Kazama siblings to guarantee her victory. But when Sakura's clubmates, Chitose Karasuyama and Roka Shibasaki, enter the race as well, the girls' competitive energy is unleashed and the contest immediately develops into an all out battle where no victor is certain. What's more, Noe, fed up with Sakura's constant teasing, has no interest in helping her win, and the battle rages not only on the field, but between the divided team members.

After finishing their "debut," Kate, Emilico and three other pairs who started with them begin a new life as adults.

In a quiet rural town, the spotlight of a local junior high school football team rests on one player: Ashito Aoi. Known for his unpredictable moves and self-centered playing style, Ashito is the sole powerhouse pushing his team through an important high school preliminary tournament. However, their win streak is short-lived—an opponent causes Ashito to lose his temper and act violently, resulting in his removal from the rest of the game. Without their star player, the team is quickly eliminated from the tournament. Just as he believes all hope is lost, Ashito is approached by a youth team coach named Tatsuya Fukuda who senses potential in him, and Fukuda invites him for tryouts in Tokyo. In an unfamiliar setting surrounded by talent, Ashito must bring out the best of his ability to prove himself and secure what could be a life-changing career.

Following the conclusion of the large-scale coalition campaign, the entirety of China is in a state of economic recovery. The victor of the battle, the state of Qin, is no different. There, the political parties led by Ying Zheng and Buwei Lü continue their inner conflict. Having played the role of king in the coalition battle, Zheng has the trust of the people—but Lü is far from out of the fight. In 18 months, he plans to interrupt Zheng's coming-of-age ceremony. Meanwhile, a Zhao army numbering 20,000 troops has set out toward Qin. In the royal court, due to the lack of generals capable of responding to the incoming threat, Lü slyly suggests that Zheng take command. However, Cheng Jiao, Zheng's half-brother, volunteers instead. As they grew to trust each other during the coalition battle, Zheng now accepts Jiao as his replacement. However, the Zhao forces retreat a mere half-day after clashing with Jiao's army. With trouble quickly brewing in the shadows, the internal struggle of Qin is only complicated further. There are only two men Zheng feels he can rely on: Bi, a general who commands 30,000 men; and Xin, the leader of the Fei Xin force.
