I Am the Demon King of Time, and My Thigh-High-Wearing Sister Turns Me In to the State

In 2333, Blue Star is overrun by evil beasts, and humanity faces annihilation. To fight these monsters, some people awaken special professions, such as artifact refiners, sharpshooters, and mechanical experts. Wu Linjun awakens as a Kamen Rider, able to take on the forms of various Riders. After his parents are killed in an accident, he and his younger sister depend on each other. At her urging, he joins the nation's Dragon Squad, where he meets all kinds of teammates. Killing evil beasts of different grades can drop the corresponding Rider gear, such as Rider Cards or Ridewatches. There is also a small chance of obtaining a trait that boosts his strength. And so, a dedicated hunter of evil beasts is born. His icy female superior: “You defeated the highest-level evil beast all by yourself? Come to my room.” His younger sister: “That's my big brother! He's the person I admire most.” The mature beauty: “Interesting. You're just the kind of man I've had my eye on.” When Wu Linjun stands alone before all the evil beasts and faces the challenge of their leader, he simply says, “Just a passing Kamen Rider. Remember that.”
