Yokaiden

OEL manga series by Nina Matsumoto (aka SpaceCoyote), currently consisting of two volumes. The story revolves around Hamachi, a young boy fascinated by Yokai (Japanese spirits) even while others are repulsed by and/or terrified of them. After a vengeful Kappa, Madkap, takes his grandmother's spirit, Hamachi journeys into the Yokai realm in order to seek his own vengeance. Along the way, he meets a lot of strange, strange Yokai.

"Tengu: That's the oldest trick in the fairy-tale book!"
 * All of the Other Reindeer: Inukai Mizuki is ostracized because of his love for Yokai. Hamachi is too, but to a lesser extent.
 * Anachronism Stew: And how!
 * Berserk Button: Don't make fun of Lumi. And especially don't make fun of her in pun form.
 * Dangerously Genre Savvy: Hamachi tries to retrieve a sword from a Tengu by offering him a piece of bamboo he claims can see far into the distance, reenacting the classic tale of the boy who tricked a Tengu for his invisibility cloak through similar means. The Tengu plays along with it for a moment, before calling Hamachi out on it.

"King Enma: I am the great King Enma: ruler of the underworld. Come closer, and I will show you true fear − Hamachi: I said portal to the realm, not the portal to Hell!"
 * Deadpan Snarker: Lumi.
 * The Ditz: Kuzu, the paper umbrella Yokai.
 * Embarrassing Nickname: Madkap doesn't like being called Madkap. Possibly because it insinuates that his only character trait is being mad all the time.
 * Lumi as well. It's safe to say that anyone Hamachi gives a nickname to isn't going to like said nickname.
 * Eye Scream: Although you don't get to see the aftermath ...
 * Hell Gate The portal to the Yokai realm. Not to be confused with the portal to Hell.

"Namahage: Ick! How can you wear that around your neck?! Hamachi: Don't you slice off the skin of kids' feet?"
 * Honest Axe: When Hamachi is trying to bargain with a Tengu in the Yokai realm, he offers him magic beans and a glass slipper before asking, "Did you drop the silver axe or the golden axe?"
 * Hypocritical Humor: When Hamachi shows his chopped-off Kappa foot to the Namahage, a Yokai who cuts the skin off of children's feet.

"Madkap: I don't want to hop around on one foot for the rest of my life!"
 * Life or Limb Decision: Hamachi chops off Madkap's leg after he gets it caught in a trap. Madkap isn't happy about it.

"Hamachi: Shakuhachi. Yokai guidebook. Food. Journal. Water. And my mitts."
 * Also, Inukai Mizuki cuts off his arm after a boulder falls on it.
 * My Card: Mister BetoBeto gives one to Kyumon.
 * Paper-Thin Disguise: Binzuru's Tengu disguise. Complete with a little sign that says, "Hi I'm a Tengu."

 * Water Wakeup: In the first volume, Hamachi gets one from his grandmother.
 * Youkai: But of course!
