Manabu Itagaki

The most recent addition to the roster, the charming Manabu has a prodigy's talent and was the captain of his high school's boxing team. Cheerful and a lover of bad puns, Manabu is a fierce outboxer with extremely high speed and reflexes and whose fighting style is uncanny in its resemblance to Miyata's. His most powerful technique is a furious hail of mid-power blows known as the Hedgehog or Porcupine, which was employed in an East Japan Rookie Kings showdown with his longtime nemesis, Kyosuke Imai. Outside of boxing, Manabu is employed as an assistant at the Makounouchi family's fishing business.

Itagaki's character is based on former world champion Oscar de La Hoya for his prodigy-like natural ability and good looks, whom Itagaki has admitted to idolizing in the manga. His current record as the Rookie King of his class stands at 9 Matches 8-1-0 (W-L-D), with 6 KOs.
