Bio: The daughter of Kamen Riders Decade (Tsukasa Kadoya) and Kivaara (Natsumi Hikari), Megumi grew up within the mismashed family of Hikari Photo Studio with Shigeru, the son of Diend (Daiki Kaitou), and Aiko, daughter of Kuuga (Yuusuke Onodera). She was used to her home traveling between worlds, meeting all of her parents' Rider Friends, and learning all these different ways of fighting. However, the adults of the family tended to leave her and her "siblings" with the Shiba Clan in the Sentai World during those times when all four of them had to go do dangerous Rider things together. During those "daycare" sessions, she got to know the Shiba children, especially the eldest son, Mamoru. Her friendship with him, plus her Calligraphy and Bushido training under his father Takeru, helped her deal with her growing frustration at being left behind as she got older and better trained. She wanted to go help her parents fight - even if she could only fight mooks at the time. It led to a lot of arguments with her father, who was having trouble seeing the young woman she was becoming instead of the child she used to be. One day, though, during the summer after her high school graduation, the Hikari Studio came back empty of any of the parental figures. The only thing she had to go upon was her new belt, a note advising her that it's time for her Journey across Worlds, and her father's pink camera. The last thing worried her, because she's been told that if Tsukasa leaves his camera behind, there's something truly wrong going on with him. Armed with this equipment, and with her two siblings and Mamoru by her side, she's traveling across the worlds, battling this Hell Shocker that is threatening the multiverse.
Rider Name: Shinken Rider
Identity: Mamoru Shiba, son of Takeru Shiba (19th ShinkenRed)
Gender: Male
Motif: Samurai, Shinkenger style
Kaijin Enemy: Hell Shocker; Gedoushuu
Form: Shinken Flame - His standard form, which looks like an armored form of ShinkenRed's outfit. The only other difference is that instead of the "fire" character on his helmet, it's the Shiba character instead.
Arsenal: ShodouDroid, a smartphone with a slide-out keyboard, which folds along the length to form his "brush"; Shiba Roar, his bike with the Shiba clan motif
Rider Item: His weaponry is akin to that of the Shinkengers, being of the Shiba Clan.
Finishers: WIP At the Moment
Bio: The elder son of Takeru Shiba and the latter's ShinkenPink, Mamoru was born and raised into the Shiba household in the Sentai World with every expectations that he will one day take over his father's role as Shinken Red, lord and leader of the Samurai Sentai Shinkenger. However, that soon faded once he got to know Megumi from a young age. Her tales of other worlds stirred a yearning within him - a yearning to travel across the worlds by Megumi's side. Yes, her side, for he also developed a big crush. However, this caused some conflict within him, for he feels that if he does go with Megumi one day, he would have to give up his duties as a Shiba and a potential future Shinkenger. And by doing so, he would greatly upset his parents - especially his father, whom he was close to. Unknown to him, though, Takeru had realized that Mamoru may not be the next ShinkenRed. Thankfully, Mamoru's sister secretly told her father that she would gladly take her brother's place if it meant for Mamoru to follow his heart in peace. With that in mind, Takeru and his old friend, Genta (ShinkenGold), worked together to create the Shinken Belt. This way, Mamoru can still follow his duties as a Shiba, but as a Rider by Megumi's side instead of as a Shinkenger. Thankfully, the belt was finished just at the same time as Megumi gained her belt. So, with both belt and his family's blessing, Mamoru left his homeworld to help Megumi save all the Rider worlds from Hell Shocker.
