KUSAKA Riki

Shuu Ito, 39, is still an active bicycle racer. His wife Kazumi, 35, is a housewife in her prime. Both Shuu and Kazumi have grown up, but the love of Japan's strongest couple still runs hot. And then there are the five handsome young men who hang out around the Ito household. They are new bicycle racers who look up to Shu as their mentor! The Ito family only grows stronger, as the new chapter of Keirin Yarou begins!

Japan's population is becoming older. With the advances in medicine and technology, the average age of an individual has steadily risen, but the birth rate has dropped significantly since the "baby boomer" generation. This leads to a natural imbalance between the elderly versus the younger, working class population. What becomes necessary are people like Onda Momotaro to nurse the elderly gentlemen and ladies that are becoming increasingly senile. His introduction into the "industry" of taking care of the elderly was shocking. What he saw was an elderly man being tied down to a bed for his own safety, while the nurses and caretakers consider this a "necessary evil." Momotaro is determined to help the elderly and bring back their smiles.

Sawako, a 22 years old female pilot working for a local air freight service provider, WING. One year ago, she married her then-trainer, Tametomo, who was 37 years her senior. The marriage lasted only 3 days, after Tametomo was killed in his plane crash. It took Sawako a long time to recover from Tametomo’s death, not without his step-son’s constant side-by-side support. One year later and lives moved on – Sawako is now living with Tametomo’s step-son, Daitarou, who would still call her ‘ma’ from time to time… But the thing is, he is actually 7 years older than Sawako, and he has already fallen in love with her a long time ago….
