Ryōgi

is a member of the Byakuya Gang.

Background
In his early childhood, Ryōgi lived a simple but carefree life with his parents. He would stay at home with his mother while his father would go off to shinobi missions with Gekkō. One night, to Ryōgi's horror, his father returned home mortally wounded and soon after dead. Immediately afterwards, the assailant, revealed to be Gekkō, killed Ryōgi's mother. As he moved to kill Ryōgi, in fear for his life, the traumatised boy awakened his Ice Release to repel the man. Ryōgi passed out from the events. Seeing Ryōgi's power, Gekkō altered Ryōgi's memories to think another man killed Ryōgi's parents. Taking the orphan with him, Gekkō told Ryōgi that his father and Gekkō were secretly also working part of the noble thieves, the Byakuya Gang, in the goal of bringing true justice to this world and change it for the better. Ultimately, Ryōgi decided to join the group as well.

Personality
In his tender years, Ryōgi was very cheerful child with great admiration for his father, hoping to become like him. After losing his parents and learning the "truth" about the world, Ryōgi is a rather mellow individual, very mature for his age. He is very polite and enjoys meeting new people. He is also shown to be very intelligent, repeatedly beating Shikadai Nara in shōgi. He is also very loyal to the Byakuya Gang, so much that there is no doubt from Gekkō that he would never betray them. Also, similar to Shikadai, Ryōgi believes that not everything in life is so straightforward. He believes strongly that the world is corrupt and the only way to change it for the better is to make tough decisions.

Abilities
Ryōgi possesses the nature transformations Water and Wind Release, which he can combine to use Ice Release. With the kekkei genkai, he can use it for a variety of ways including freezing objects on contact, lowering his body temperature, and freezing the ground to immobilise individuals. Offensively, he can launch a barrage ice darts of such intensity, that even blocking them can cause the person severe bodily harm. He can also combined his Ice Release with Yin Release to produce powerful genjutsu. Ryōgi is also capable of performing hand seals with only one hand.

Byakuya Gang Arc
As the Byakuya Gang began operating in Konohagakure, Ryōgi and his father began scouting the village to better plan their heists. Eventually, Ryōgi met Shikadai, where the two quickly grew close do to having similar outlooks on life and enjoying to play shōgi. Later, during one of his missions, Ryōgi was intercepted by Team 7. He was able to evade their trap. After which, he lured them to a poor village that the Byakuya Gang recently helped, trying to show the noble nature of his gang's intentions.

The following day, during another heist, Ryōgi and his allies were intercepted by Team 5. During the escape, Ryōgi injured Metal Lee. Later, Ryōgi met again with Shikadai to play more shōgi, and properly met Boruto when he came to show Shikadai new games. Days later, while playing with Shikadai, the Konoha-nin confronted him about his allegiance with the Byakuya Gang, having already deduced the truth. Ryōgi denied the claim, until Shikadai tricked him into revealing the truth. Shikadai tried to convince Ryōgi that this path as a so-called noble thief would only get him killed, Ryōgi rejected the claim, saying that Shikadai has been lucky to live a peaceful life and as such, never had to try hard at anything. Ryōgi then retreated.

For the Byakuya Gang's final heist, they spread rumors about the Kaminarimon Company being a corrupt organisation that was unfair to its workers. This combined with the growing support of citizens in the village and placing multiple people under genjutsu to further the charade forced all active ninja in the village to work and pacify the protestors from growing violent. During which, the gang made their move on the Ninjutsu Research Centre, where they stole Centre's entire data on world ninjutsu. As the gang made their way for the country border, they were found by Team 10 and Boruto, who followed the gang thanks to a locator Katasuke Tōno placed on Gekkō. Ryōgi and Gekkō made their retreat while the rest of the gang held off their pursuers, however Shikdai and Boruto managed to slip past them and followed Ryōgi and Gekkō onto a train.

As Shikadai and Boruto confronted the two thieves, Shikadai again tried to reason with Ryōgi, who still rejected Shikadai's words, while also struggling to maintain his composure as he began suffering a massive headache. Gekkō then comforted Ryōgi (while really strengthening the curse seal) urging him to continue fighting, to which he then captured Shikadai and Boruto in a dome of ice. Gekkō then made his escape. As Ryōgi continued to hold them off, his cursed seal began acting up, making him attack recklessly. Shikadai employed Boruto's aid to get close enough and break the genjutsu. Finally seeing reason and remembering the truth, Ryōgi accepted defeat, but also fell into sorry at having nothing left. Shikadai insisted that he has come to understand Ryōgi better and will help him to rediscover himself. Ultimately, the Seventh Hokage captured Gekkō, who along with Ryōgi was arrested and put in prison. However, Shikadai remained in contact with Ryōgi.
