Lessons learned from KR

[NateRiver]

When your friends try to contact you, booby trap your entire house.

 

[Oblivion]

When your friend turns into a grey monster due to human evolution, reject him and then accept him. Repeat 3 times and you two are now buddies.

 

[Switchblade]

When being attacked by a monster, call your friend who's a Kamen Rider, scream something like "Takumi! Orphenoch!" and then hang up. He will totally know exactly where you are and be there within two minutes.

For a hero who can withstand blades, bullets, and energy blasts, there is no danger worse than falling into water.
