Tolong jelaskan mengenai Rival dari Days (manga)

Indou is one of the main characters of Yasuda's previous manga "Furimukuna Kimi wa." His duo with fellow genius soccer Narukami has made their school, Sakuragi High School, become a National stronghold. He's a genius playmaker who displays amazing field vision so that he can give precise assists. He has a strong rivalry with Seiseki's Mizuki, who like him is called one of "Tokyo's big three." Just like Mizuki, Indou is also one of the "top-tens," a nickname given to those High School students who have received an offer by a professional soccer team. Tsukushi meets Indou by coincidence in a train, and then Indou invites him to play a futsal game. Later, Seiseki plays against Sakuragi in the Tokyo qualifiers to the Summer Inter High School tournament.

Narukami is the other main character in Yasuda's previous manga "Furimukuna Kimi wa." His duo with fellow genius soccer Indou has made their school, Sakuragi Academy, become a National stronghold. A short and frail guy, who was unable to play soccer before high school due to his bronchial asthma, he turns into a different person while playing, to the point of becoming bullish and arrogant. He's a superb forward, incredibly fast and precise. Tsukushi has Narukami in great regard, due to his skill despite being as short and frail as he himself is.

The captain of Touin Academy, Takumi is the younger of the three Hoshina brothers, who are nationwide famous, with the oldest being professional and the other one being the top scorer in the collegiate league. Takumi plays as a libero, and is also one of "Tokyo's big three." Just like Mizuki and Indou, Hoshina is also one of the "Top ten," and will play for a professional team as he graduates. Although a great dribbler, Hoshina generally sticks to solid defense and is depicted as risk-averse and a safe player, and in charge of coordinating his whole team. Seiseki plays Touin Academy in the finals of the Tokyo qualifiers to the Winter inter high school tournament.

The captain of Seikan High School in Aomori, that Seiseki plays against during the summer camp. Just like Mizuki, Taira will be joining the Kashima professional soccer team after graduation. Taira is a playmaker with a strong physical ability, able to send powerful yet precise passes. His duo with Seikan's star rookie forward Himura allows Seikan to go to the Winter Nationals.

Seikan High School's ace striker, Himura is a very fast forward, a skill that is taken advantage of by Taira. As a freshman, he shows a strong rivalry with Kazama over who's the best rookie player of the two.

The star forward and ace striker of Ichiboshi Academy, he's the only 2nd. year student in the "top ten," meaning he already has a professional team offer. A soccer prodigy, Aiba has been the top scorer in every single category he has played. An outstanding dribbler and all-around forward, he's nationwide famous, and the center piece in his school offensive soccer style. As part of the same generation, Kimishita and Oshiba both feel a strong sense of rivalry towards him.

The captain of Ryouzan High School, champions of the Summer Inter High Schools tournament. Another of the "top ten" players (of which his team has other two), Katou is boasted as the best high school defensive midfielder and likely the best player overall, which has granted him a seat in the National team of his category. He's well known for his stamina and his tireless leadership and grit, with rivals commenting on how his face would show up anywhere around the pitch, a result of his tireless energy and his superb understanding of plays, characteristics that other players see as well on Tsukushi, with Jin suggesting Tsukushi that Katou is the player that he should try and look after.

Ryouzan High School's number 10, and a key member of the National team of his category, Ikariya is a superb offensive midfielder, nicknamed "Japan's Treasure." Ikariya is incredibly popular and is even sponsored for advertisement. A very versatile and highly technical player, Ikariya possesses amazing dribbling, ball control, incredible reaction times, and long distance shooting with his left foot, which is the reason for his other nickname, "The left of God." He's the second of Ryouzan's "top ten" players.

Takagi is the third of Ryouzan High School's "top ten" players, the most of reserved of the three but arguably the most dangerous of them. Takagi is considered the best fullback in the history of Japanese High School soccer thanks to his strong physique, amazing speed and crossing ability. Since both Katou and Ikariya are often missing due to their playing for the National team, it's Takagi who is at the core of Ryouzan's team, and who gets the most respect from his fellow players. A country bumpkin, he often finds himself at odds with the celebrity of both Katou and Ikariya.
