I, Kurikara Ryuu Ou, have returned with the handbook all God-kind will find themselves in possession of (if they want to live).
Genbu
1. Dress up in a maid's costume.
2. Crawl all over his staff, cooing about how much you love large pieces of wood.
3. Allow him to find you in his personal chambers molesting a turtle shell.
Conclusion: With age comes experience.
Rikugou
1. Sympathize with him when he begins on a hate rant about Souryuu.
2. Appear intelligent and fascinated with all aspects of (yawn) divination.
3. Come to him one day exclaiming over how you had a vision of Souryuu's gruesome demise.
4. Stage said demsise and paint yourself in blood.
5. Don't let him look too closely at the 'corpse'. But then, it isn't likely he'll even care at that point. If you know what I mean.
Conclusion: It can't be said that Souryuu's tendency to be an asshole is completely without merit.
Kotarou
1. Look at him.
Conclusion: I'd hate to see the size of the Tengu population if he were female.
Kojirou
1. Act like a boisterous idiot (observe Kotarou for help on this)
2. Declare your adoration with a great deal of lightning effects and black feathers
3. Drag him off before he gets a chance to defend himself.
Conclusion: It might actually be easier to blugeon him before and after attempting any of this.
Good luck to you, my brave traveller. May your wanderings have many stops along the way!
