Taiyou Sakaki, a guy who never ate ramen before eats it for the very first time after a fight! He then develops an interest in ramen, gets a job in the same ramen shop and hopes that everyone will be able to taste a "rainbow" inside every ramen he will make. Later, he creates a Ramen Club and together with Yuuichirou Akagi, Hiroshi Hasegawa, Natsuki Ouka and Hikari Harada strive to take part in Ramen Koushien. (Source: MU, edited)
