Daily Comics: I, Open the Box and Have the Full Power of the Knight

Ryuunosuke, who traveled to the manga world, gained the power of Kamen Rider Kyokushin, and by completing tasks, he could also gain the power of other knights. I was originally prepared to enjoy him, but I unexpectedly found that the world was not as simple as imagined. An unidentified life form that was resurrected at the Kurodake ruins for unknown reasons. An angel who started hunting humans for unknown reasons. The terrifying vision of being suddenly pulled into the mirror. What is the connection behind these horrific incidents? In order to investigate the cause of these anomalies, Ryunosuke began to investigate. This is my first time writing, so I want to practice the world view of Kamen Rider plus the manga first. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
