Evil and the Bean

, also known as I Oni Have Eyes for You, is the 308th chapter of the manga it is also the first and only chapter of the Evil Oni Arc.

Soun, Genma and Ranma are all visiting a local temple to assist with the re-sealing of an ancient, evil Oni. The box it's kept in has grown old and it seems that the creature will soon break it's bonds. Happosai soon arrives and blows his nose on the paper seal that was to be used on the Oni, which allows the monster to escape.

Releasing the Oni
Ranma has gone with Soun and Genma to a local temple, where a Priest has called them to in order to help him defeat a demon. When they arrive the Priest explains that 1,000 years ago when a High Monk(ey) fought with a demon and ended up trapping it within a box.

The group then go into a temple, where a box on rattles slightly on a table. Soun asks if this is where the demon is sealed, to which the Priest explains that it is, but due to the age of the seal the text has almost completely faded so won't be able to hold the Oni much longer so they'll have to catch it with a new seal.

At that moment the Oni begins trying to break out, but Soun, Genma and Ranma quickly react and hold the lid tightly shut while the Priest prepares the new seal. However, just before the Priest can place the seal, Happosai appears and uses the seal as a Handkerchief due to his getting a runny nose from it being winter. Ranma then calmly walks over to Happosai.

 * The striped outfits which Ranma wears on this chapter's title page and that worn by the Oni are likely references to the outfits worn by Lum and Ten from Rumiko Takahashi's previous manga series, Urusei Yatsura.
 * The same could also be said for the horns which appear on those possessed by the Oni.
