This cube craft paper toy is the Ryohei Sasagawa, based on the anime and manga series Reborn. This paper craft model is designed by Alonso Jacobo. Hayato Gokudera is a fictional character in the Reborn! created by Akira Amano. He has also appeared in other media from the Reborn! franchise including video games and light novels. Ryohei is portrayed as one of the series' protagonists, and is introduced as the energetic member of the boxing club at Namimori Middle School. He would often attempt to get the main character, Tsuna Sawada, to join his club, and in response, Tsuna's home tutor, Reborn, attempts to get him to join Tsuna's personal Mafia family. His role is initially minimal, usually only having brief appearances since his introduction. Becoming the Vongola Family's Sun Guardian is what leads to his first significant and recurring involvement in the story.
Ryohei Sasagawa is Kyoko Sasagawa's older brother who is obsessed with boxing. His motto is to live "to the extreme!", which he applies to everything he does. As such, he prefers to fight his opponents head on, seeing any disadvantage as a chance to improve his fighting skills. He even barged into a zoo, expecting to fight a bear, but ended up fighting a lion instead. Every time he sees Tsuna and his friends doing something strange, he gets riled up and wants to be a part of it. Due to Ryohei's enthusiasm, he often rushes into things without fully evaluating the situation, which often results in his injury. He also has a short memory and forgets many important details, something his future-self overcame by writing memos. Ryohei is always hiding the truth of his actions -the actions relating to the Mafia- from Kyoko, due to an incident that had happened while they were in primary school. Some high school students who did not like Ryohei used Kyoko to lure him into a trap. In his attempt to rescue her, he suffered severe injuries, which resulted in the scar on his left temple. Kyoko still feels responsible for this incident, though she accepts that he needs to fight. He is deeply concerned for Kyoko's safety, so he covers up his actual life-or-death battles with the cover story of "Sumo matches". He is known to have great boxing skills in the Vongola Famiglia.
