Katsumi Minato

"Color me with your power! Ruebe!"

- Transformation call, shared with Isami Minato

Katsumi Minato (湊) is one of the protagonists of Ultraman R/B and the eldest son of the Minato Family. He is the human host of Ultraman Rosso.

Personality
Being the eldest son of the family, Katsumi puts the importance of family above everything else. One of the biggest instances is his decision to abandon his lifelong dream as a baseball player to support his father's specialty store ever since mother disappeared. This in turn allows him to have a keen fashion sense and determine the best clothes for his clients.

Although Katsumi suffers from sibling battles with Isami, both of them willingly cooperate with each other when facing opponents. Despite being a critical thinker, he is also hot-blooded and incapable of observing his surroundings when playing Baseball.

Ultraman R/B
Katsumi encountered Grigio Bone on his missing mother's birthday and received both R/B Crystals and R/B Gyro while fleeing for his life. After his initial fight as Rosso, Katsumi became hesitant due to the responsibility of an Ultraman until an encounter with Black King changed his mind. Ever since then, he would join Isami in fighting as Ultramen to defend the city against monster attacks.

While training for his coach's baseball match, Katsumi's determination puts him in a dilemma for either saving the city or winning a match. Fortunately, said coach took his place as a batter while Katsumi halted Red King's assault with the three Crystals he obtained earlier.

Unknowingly to them, their battles were being watched and analysed by Makoto himself, who presented them with several trials such as capturing an old friend within Mecha Gomora. When Makoto revealed to them his true nature and origins, the brothers fight against him directly, when he transforms into Ultraman Orb Dark and they were easily defeated.

After that, Katsumi and Isami set out to do some training in the mountains so that they could beat Orb Dark. On their second training session, the brothers with some indirect help from Asahi found the Victory Crystal in a cave, granting them the power of Earth. With this new power and their training, they challenged Orb Dark to a rematch and defeated him. The brothers then took the Orb Ring NEO from Makoto.

Later, the next challenge they faced was Horoboros, who the brothers lose to despite having the Orb Ring NEO. After their defeat, Makoto reclaims the device and transforms into Orb Dark to fight Horoboros. Unable to transform, the brothers could only watch Makoto fight the beast and after his "victory", they confront him in public, telling everyone that he is behind the monster attacks but nobody believes them. Isami gets upset, so Katsumi reminds them about why they fight as Ultraman and that cheers him up. The next day, Makoto summons Bezelb to fight it as Orb Dark to further promote himself but the brothers show up and defeat the Bezelb before he could, angering him. Orb Dark tries to attack them but Horoboros reappears and evolves. It defeats Rosso, Blu and Orb Dark before disappearing, but Katsumi and Isami are badly injured in the process and they detransform in from of Asahi, who finds out about their alter egos before the two of them are sent to a hospital for treatment. After they reawaken, they try desperately to hide their identities from Asahi but it is too late. Horoboros appears yet again and the two brothers transform and fight, coming up with a strategy to put it in hardened stone, but it failed. With Asahi returning the Orb Ring NEO to them, they used its power and finished off Horoboros with the Triple Origium Ray.

After that, they were faced by a vengeful Cereza, who transformed into Grigio King via Saki's Gyro. The brothers try their best but they are unable to defeat Grigio King, exhausting all of their techniques. The brothers return the next day after a short recovery period, but even with a new strategy, they were unable to defeat Grigio King until Asahi reminded them of their mother's words - that when the two of them are together, they can do anything. With that, they unlocked the power of Ultraman Ruebe, who fought Grigio King and destroyed it.

Katsumi and Isami meet Saki Mitsurugi several times, mostly while she is with Asahi and they find out that she is behind the recent monster attacks. The two of them become suspicious and further antagonize her when she announces her plan to turn Earth into a bomb to destroy Reugosite. Later on, the brothers had their Gyros stolen by Saki Mitsurugi after King Joe attacks. Back at Quattro M, Asahi explains to the brothers about Saki's past and while Katsumi sympathizes with her, Isami is determined to stop her. Confronting Saki to get back their stolen Gyros when Gomora attacks, they also try to convince her that defeating Reugosite at the cost of the planet is not what her brothers would have wanted, but she disagrees. The brothers fight her as Grand King Megalos and defeat her though Katsumi was hesitant to fight while Isami attacked without a doubt. After she tells them what happened to their mother, Mio, she transforms into Horoboros but like before, Katsumi hesitated in fighting her. This disagreement causes the brothers to not be able to use the power of Ruebe but after clearing their disagreements and deciding to protect what is important to them; their family, they can once again use the power of Ruebe, which they used to beat Saki but not finish her off. After chasing Saki back to a lab, the brothers and Asahi witnessed the return of Mio Minato.

Transformation
{{#tag:tabber| Rosso= Katsumi takes a R/B Crystal from the R/B Crystal Holder and flips out the side horns of the crystal. He then inserts the crystal and the R/B Gyro opens. The Gyro is placed at chest level and the handles are pulled twice. Katsumi then thrusts the Gyro forward and pulls the handles one last time and places the Gyro on his chest, before transforming utilizing the elemental power of the crystal. When swapping crystals with Isami, instead of getting the crystal from the holder, the new crystal will appear and fall from above. The same sequence continues afterwards. {{#tag:tabber| Flame= {{#tag:tabber| Standard= {{quote|Enshrined by Fire. The Crimson Flame!|Activation announcement for Flame}}
