After having his plan to get Akane unconscious thwarted by Ranma, Happosai plans to use an Incense of Spring Sleep which will force Ranma to sleep until spring. Unfortunately the next morning Akane smells the incense instead, although initially appears unaffected by it.

Once Akane gets to school, however, the incense takes affect which puts her to sleep, causing trouble for the other students due to her violent outbursts as she reacts to her dreams.

Major Events

 * No major events occurred in this arc.

Changes in anime

 * OVA starts with a non-canon crossover mini-episode, with Urusei Yatsura and InuYasha. Characters from both franchises will cameo throughout the main story.
 * Happosai never tried using knock-out incense on Akane. Instead, Ranma prevented his usual doing his usual lingerie stealing.
 * The meal that Akane prepares for Ranma in her first dream (where she is one married to Ranma with Ukyo and Shampoo) still has a duck that looks like Mousse, but also a pig that resembles P-Chan.
 * Ranma doesn't try waking Akane with water (so she never dreams of drowning).-
 * Just like Kuno, Gonsunkugi wanted to try waking Akane with a kiss (he even dressed up as a prince).
 * OVA skips the dream of a Happosai demon stealing her underwear.
 * Akane has an Indiana Jones-like dream and wreaks havoc through school, the city and finally Shampoo's cafe (There she has a calmer dream about winning an eating contest, but her award is a kiss from Happosai, which once again makes her attack everything).
 * Dream with evil queen Kodachi is extended, but once Ryoga shows up and attacks Ranma in real life, Akane's dream changes to reflect that, turning everyone into characters based on Journey to the West.
 * From this point, manga and anime go in completely different directions, aside from 1) Akane having a dream about Prince Ranma and 2) Nabiki having Incense to sell. (except for this one allegedly would make its victim in a smooching mood. Shampoo and Ukyo want to buy it, but the story never mentions it again).
 * Cologne has a Spicy Incense that can wake Akane. However, Akane avoids all direct attacks (she's having a war dream) and the only way to give her Waking Up Incense is through mouth-to-mouth. Kuno, Gonsunkugi, Happosai, and Ryoga all want to do it, but the side effect of incense mess with their heads. They need to be taken down with yet another incense that makes them see everyone as Akane (including each other), which leads to a gross make-out between the four of them.
 * In the end, it's up to Ranma to wake Akane with Incense in his mouth, but he's so nervous he accidentally swallows it. When all seems lost Akane gets awoken by passing by Kasumi (it's because Incense of Spring Sleep was made as a defense against assassins and Kasumi has absolutely no blood lust in her). OVA ends with Akane and Ranma walking together, Akane tries to tell him about her dreams, but it ends with their usual arguing.

Characters Introduced
