Jin

Jin is an operative of the underground cyberterrorist group MetsubouJinrai.NET and the secondary antagonist of the first Reiwa era installment in the long-running Kamen Rider franchise, Kamen Rider Zero-One.

History
After being given a Zetsume Riser by Horobi, Jin grabs a pistol and goes out to hack a HumaGear. Approaching Abdominable Collapser Taro, Jin places the Zetsume Riser onto him and turns him into the Berotha Magia

As Kamen Rider Zero-One fights the Magia, Jin watches with amusement and delight. While he is watching a haywire HumaGear attacks him, but Jin casually shoots the HumaGear while laughing.

After Zero-One destroys the Magia, Jin reports back to Horobi about the new Rider, to which Horobi expresses interest.

Personality
In contrast to his partner Horobi, Jin has a very chaotic and erratic personality. He enjoys causing havoc while laughing amusingly and shows little regard for others.
