Magical Girl's Knight Brother

After a catastrophic accident, Tang Zijun found himself transported to a parallel world, accompanied by a mysterious Kamen Rider belt. As he navigated this new reality, he discovered a hidden underworld known as the Mirror Dimension, teeming with monstrous creatures. Over the course of several years, Tang Zijun single-handedly eradicated the threats lurking within the Mirror Dimension, adapting to his new life in the process. Just as he had begun to settle into a peaceful existence, he stumbled upon a shocking secret: his sister was leading a double life as a magical girl. This revelation raised more questions than answers, prompting Tang Zijun to wonder if there were other factions at play in this world, and whether the Mirror Dimension was the only evil force at large. As he grappled with these concerns, Tang Zijun was compelled to reassess his own role, and after seven years of retirement, he reluctantly donned his Kamen Rider belt once more, ready to face whatever dangers lay ahead, warning his enemies: "Don't blame me, blame yourselves for messing with the wrong people." With a fierce determination, he transformed, declaring "henshin," and embarked on a new journey to protect his sister and uncover the truth about this complex world.
