Kamen Rider Yakui. The Rider who collects misfortune.

Kamen Rider Yakui's henshin steps:
1. Fasten the Yakui Driver belt.
2. Grab the Yakui Phone and input "8-9-1-Enter" (note that 891 is read as "yakui", which means "misfortune" in Japanese). The phone will then say "Standing by...."
3. Spin yourself round, raise your right arm, and cry out "Henshin!" while the phone makes a standby noise.
4. Put the phone on the belt and it will say "Complete!" (Does not work on anyone. For users with no animal, demon or goddess blood, the phone will say "Error!" and the belt rejects from the user)
The henshin steps above are based on Kamen Rider 555. But they are just fan opinions.
