After learning from Ursula and the Shiny Rod that she needs to find something she is lacking in order to unlock the fourth word, Akko joins Lotte and Sucy as they visit Lotte's home in a remote Finnish village. The next morning, however, they discover that Lotte's parents and their neighbor have become infected with the rare Greenman Disease, which will gradually turn them into moss until they wither away. Needing five particular ingredients to make an antidote, the girls set off in search for them, but Akko's lack of patience proves to be an issue. When Lotte and Sucy also succumb to the disease, only Akko is left to get the remaining ingredients and is forced to learn patience in order to deal with a spooked reindeer and a yeti artisan who is lacking in self-confidence. Realizing the importance of being patient, Akko manages to unlock the Shiny Rod's fourth word and finish the antidote, restoring everyone to normal.
Back at her dorm, Akko reveals the truth regarding the true purpose of the Shiny Rod, which baffles Lotte and Sucy. Akko is determined to unlock the remaining words but is unable to understand them. Although Ursula helps out, she remains quiet what their actual meanings are as she reminds Akko that they can truly be unlocked if Akko take the lessons to heart. Suddenly, one of the Shiny Rod's stars activate and Ursula understands that they must head to Lotte's hometown in Finland, as it will actually help Akko.
The trio arrives to the Finnish town. They go to a shop which belongs to Lotte's family, who joyfully greets their daughter and her friends. Everything seems in order, except that Akko didn't like the pie and was unable to wait in the sauna. Next morning, the girls found Lotte's family trapped in some sort of moss which is later revealed to be an ancient sickness, called the Greenman Disease, that affects the pies. Lotte's mother reveals a book that contains all the ingredients needed to create an antidote.
The journey is long as Akko is unable to wait for the ingredients to fully mature. When they return, Akko and Lotte find Sucy suffering in the moss, the same effects as Mr. and Mrs. Yanson. Soon, the disease catches up to Lotte, leaving Akko to create the antidote herself. The fourth ingredients is to be obtained from a reindeer who belongs to a man named Nicholas. Akko chases after the reindeer, which leads to the reindeer grow some contempt for Akko. After containing the reindeer's dropping, Akko learns that the final ingredient needs to be made by a yeti who lives in a snowy mountain. After meeting the yeti, who is failing to make the ingredient exactly correctly, Akko's impatience gets the best of her, leading her to have an outburst, which upsets the yeti and makes him cry and run away.
Akko eventually discovers that the yeti is upset because he was greatly insulted by anonymous people on a social website. Akko apologizes to the yeti and motivates him to let go of this, saying that he shouldn't care about what unknown people on the internet think of him, and says that he is an amazing yeti who can prepare important ingredients. The yeti gets inspired greatly and quickly returns to his hut, where he creates the final ingredient perfectly. After obtaining the final ingredient, Akko finds that the reindeer has left her. Akko begins her travel back to the town with the thoughts of her friends and idol helping her to push forward. Thankfully, Nicholas brings back the reindeer to help Akko.
Akko returns and by understanding that she has to be patient, creates the antidote carefully, and then the Fourth Lost Word is unlocked, turning the Shiny Rod into a huge mixing machine, which blows away every victim's moss covering, curing them. As the trio head back to Luna Nova Magical Academy, Ursula learns that Akko has learned how to be patient and has revived the 4th Lost Word. Lotte, Sucy and Ursula congratulate Akko but requests her to be more patient from now on.
