Due to his actions and role, he is a supporting antagonist in the Wano Country Arc.
Page One is a young man of short height (slightly shorter than even his proclaimed elder sister) with longish, purple hair that is all swept off to one side while the other appears to be shaved off. He also has sharp, angular eyes with no visible eyebrows. His name is diagonally tattooed on his upper body, with "P" on his right arm, "AGE" on his chest, and "1" on his left shoulder.
In his human form, he is shown wearing a horned bucket hat and a mask covering his jaw area, both being symmetrically bi-colored. He also wears a long-sleeved shirt with a dark necktie, dark gloves, a cape, and dark pants with matching suspenders.
Page One believes that anyone rebelling against the administration of Wano should be made an example of, and thus has no qualms about a powerful pirate like him being sent to deal with such instances. As a result, he is violent in his missions, destroying multiple soba shops while looking for Sanji and had no pity for the shop owners he wrongly attacked, viewing his actions as necessary to coerce Sanji into revealing himself. He is also very gluttonous, eating the soba from one of the shops he wrongly attacked, and decided to attack a fruit shop just because he felt like eating fruit.
However, when together with the rest of the Tobiroppo, Page One seems to take a far meeker disposition, becoming flustered when his peers start looking down on him. In particular, Ulti seems to embarrass him the most with her personality quirks and overall disrespectful behavior, although he seems to still hold respect for her with the way he addresses Ulti as "big sis" (姉貴 aneki?).
Page One appears to be loyal and respectful to Kaido. Unlike Ulti, he does not behave disrespectful to him and is outraged by Ulti's rudeness towards him. Unlike Sasaki and Who's Who, Page One does not seem to have any antagonism with the All-Stars as he showed no signs of disrespect towards them nor much ambition to replace them.
He appears to have a strained relationship with Sasaki and Who's Who, as the former belittled him and called him "dead weight" while the latter was annoyed with him and Ulti due to their bickering. Although Page One is more well-mannered than Ulti, he isn't above lashing out at his superiors like King when he called them "brats". 
It is unknown whether Page One and Ulti are related by blood or not, but either one seems to acknowledge the other as their sibling. Page One specifically refers to Ulti as "elder sister" (姉貴 aneki?), she being two years older than him, while Ulti refers to him as "Pay-tan" (ペーたん Pē-tan?, VIZ: "Pay-Pay"), "-tan" being a more diminutive version of the name suffix "-chan" (usually used to address females or children in a "cute", affectionate manner), much to his annoyance.
While Page One and Ulti seem to be very close, Page One is shown to be often exasperate and embarrassed by Ulti's fickle demeanor towards their superiors and crewmates. Not even Page One fully exempt from the same hostility Ulti extends to the rest of their crew, especially when he attempts to rein her personality in, which makes Ulti snaps at him for telling her what to do. Due Ulti being more overtly attached to Page One than the other way around, he finds Ulti's protective clingily behavior towards him to be irritating and constantly rejects her demands for affections. This causes their relationship to be rather volatile, as Ulti's mood towards him can range from supportive to demanding, to abrasive and outright violent, usually escalating the more he tries to rebuff her. For example, during their search for Yamato, Ulti chased after Page One, even latching onto and forcing him to give her a piggyback ride at one point, completely ignoring his protests to leave him alone.
Despite his vexation towards Ulti, Page One does cares about her, showing concern when she was hurt during fight against Luffy and worrying for her after she was attacked by Yamato, asking medics to tend to her.
Abilities and PowersEdit
Being considered one of the strongest six Shinuchi, Page One is very formidable in terms of combat ability, despite his young age. He was able to hold his own against a Raid Suit-wearing Sanji for some time.
- Further information: Ryu Ryu no Mi, Model: Spinosaurus
Page One ate from the Ryu Ryu no Mi, Model: Spinosaurus, an Ancient Zoan-type Devil Fruit allowing him to transform into a spinosaurus. In his full-beast form, he possesses tremendous strength, particularly in his jaws and tail, able to effortlessly wreck buildings using them. In his humanoid hybrid form, his arms become long enough to use offensively and hold great strength as well, being able to overpower a kick from a Raid Suit-empowered Sanji and send the Straw Hat cook crashing through several houses. As an Ancient Zoan type, Page One enjoys a high amount of durability, able to recover quickly from strong attacks dealt to him by Sanji in his Raid Suit and a Gear Third-using Monkey D. Luffy.
Wano Country ArcEdit
Page One and X Drake were sent to the Flower Capital by Queen to kill a soba stand owner named "Sangoro" (Sanji of the Straw Hats). Page One then went on a rampage, attacking soba stands in search of his target. Sanji eventually came and attacked him, and Page One contacted his comrades to come to their location as he confronted the cook. Sanji donned his Raid Suit, and when Page One attempted to attack him, Sanji turned invisible and kicked Page One in the stomach. Page One then transformed into his hybrid form and swiped at Sanji with his arm, overpowering Sanji's kick and sending him crashing through several buildings. Thinking Sanji was dead, Page One prepared to bring him to Kyoshiro, only for Sanji to drop down from above and attack him again. The outcome of the fight was not shown, but Sanji was able to escape the Flower Capital.
On the day of the Fire Festival, Page One arrived at Onigashima with the rest of the Tobiroppo. They then sat down to wait to meet with Kaido and bickered amongst themselves. When Kaido arrived, he gave them the mission of finding his "son" Yamato, saying he would let them battle one of the All-Stars for their position if they succeeded. While searching for Yamato inside Kaido's castle, Ulti tagged along with Page One and forced him to carry her when she grew tired. After tumbling down some stairs, they encountered Luffy. During the ensuing clash, Page One transformed into his full-spinosaurus form and was then struck by Luffy's Elephant Gun, with Ulti consequently being knocked out by Yamato.
After recovering from said scuffle, Page One tried to shake Ulti awake and asked for medics to tend to Ulti. Once she awakened and showed that she was fine, Page One left her behind to chase after Yamato and Luffy. As the Ninja-Pirate-Mink-Samurai Alliance waged war on Onigashima, Page One and Ulti received a call from King informing the Tobiroppo that the challenge for an opportunity to fight the All-Stars was cancelled, and that they were to stop the enemy alliance from getting to the roof of the dome, where Kaido was fighting the Nine Red Scabbards.
Page One and Ulti later attacked some samurai who attempted to stop the two from reaching Luffy. After Usopp launched an attack on Page One, the two Tobiroppo chased after him and Nami.
