RIDER TIME: Kamen Rider Shinobi - Season 1 Episode 1 First NinPow! Volume: Hattari's Love is Unrequited

As the episode opens Rentaro faces off against his sister Iroha in a ninja match, but he proves to be unable to beat her as his fire ninpo is too weak and she simply reflects a stronger version of it back at him and pinning him down with shurikens, defeating him which ends the match and earning her 10 points. The forest they were battling in was a holographic simulation which dissolves and the spectators cheer for Iroha's victory and advancement in the 5th Annual Ninjutsu Championship Tournament.
