ข้อมูลอนิเมะPopotan

A young boy called Daichi visits a mansion in an attempt to impress Asuka, a girl in his class who believes in ghosts. Inside, he meets three sisters, Ai, Mai, Mii and their maid, Mea. Unknown to Daichi, the mansion and its inhabitants are traveling through time and space. After hearing him spread a rumor that the mansion is haunted, and learning of his feelings for Asuka, the three sisters, led by Ai, agree to help Daichi fake photographs to impress her. When he shows the photographs at school his schoolmates initially believe the house to be haunted, but they later discover the truth. Believing that Asuka now hates him, Daichi returns to Ai for consolation, and falls asleep. When he wakes up, Daichi finds himself lying in a field of dandelions as the mansion disappears and Asuka comes by to see him.

Mai has never enjoyed her journey through time, and is depressed by the constant loss of new friends, and the feeling that they may be equally saddened when she disappears. While attending high school, she resolves to be firm in keeping others at a distance, but she warms to the interest shown by a classmate, Konami. Mai and Konami become friends during a class assignment in which they draw each other's portrait, even though Mai understands that their friendship must be short-lived. Konami convinces Mai that it does not matter when or where they are together, because it is the memories and feelings that are important.

Mii decides to cosplay as Magical Girl Lilo, an anime series character created especially for Popotan. Ai buys the custom-designed costume for her, and Mii runs around town trying, with varying degrees of success, to help people who believe she is a real "magical girl”. After a while she meets Miyuki, a girl about her own age, who is confined to hospital because of an incurable disease. At Mii's insistence, and with Miyuki wearing an identical costume to Mii's, the two girls set off to continue Mii's quest to help individuals in need. Eventually, Miyuki collapses due to the strain on her body, and Mii uses her power, with the help of her sisters, to heal Miyuki permanently.

Alone in the mansion's Christmas shop, Mea meets an unnamed girl who insists that Mea fixes her doll. When the sisters return, the girl vanishes, leaving her doll behind. Although she was initially reluctant, Mea decides to repair the mysterious girls' doll. The next day, Mai and Mii disappear as they are exploring an abandoned village. When the girl returns to retrieve her doll from Mea, she mentions the abandoned village when asked where she comes from, before once again disappearing. After Ai too vanishes, the mystery girl reappears. She leads Mea to the sisters, who have been placed in an enchanted dream about their greatest desires by the girl, who is a lonesome spirit. She attempts to enchant Mea as well, but fails when she realizes that Mea has no dreams. With that, the sisters are freed from their enchantment.

The mansion arrives at a place and time where an amusement park is being built. Ai finds a "popotan" who says she knows where to find Shizuku, the person they are searching for. The dandelion insists that all of the girls, including Mea, go to the spring festival and enter the “Miss Spring Bloom” contest. The dandelion then insists that the girls visit various hot springs and play ping-pong. After following the directions given by the dandlion they find their destination in ruins. There is a great field nearby, but Shizuku cannot be found, although the girls discover what she looks like from a vision in their minds. Mai and Mea are left behind when the mansion leaves without them.

The mansion reappears five years later in the same spot, this time surrounded by the amusement park that had been under construction in the previous episode. Ai uses her ability to talk with flowers and discovers that Mai is still close by. She believes that to be the reason why they have unusually returned to the same place as they traveled through time, and she and Mii begin searching. Meanwhile, Mai hears about the mansion from her friends, who think it is a new attraction in the amusement park. Mai waits to intercept Ai and Mii as they return to the mansion that evening. Despite her joy at their reunion, Mai wishes to stay and live a normal life, but after Ai explains that their bodies do not age, she resigns herself to her fate.

Thirty years after his first encounter Daichi sees the mansion again, in a photo taken of his daughter at the beach. When he goes to investigate Ai does not know how to react, and so Keith, a Guide under Shizuku, forces him to leave. Ai is smitten with Keith, until he attacks Daichi after Daichi returns to the mansion to confirm his suspicions about its true nature. The girls try to help Daichi, and they learn of Keith's true identity. Because of his deception and his attack on Daichi, Ai's feelings for Keith change. Daichi, having learned about the girls' journey, promises to keep it a secret.

The mansion arrives in the holy grounds of a Shinto shrine, where Mii meets Nono, a devout shrine maiden in training. Nono loves Christmas,[n 2] but her grandfather, the Shinto priest who is training her, is very strict and does not like her practicing non-Shintoist ways, especially as she had been so devout in her Shintoistic training. However, Nono cannot seem to ignore the temptations of the mansion's Christmas shop and visits repeatedly until, against Nono's wishes, Mii persuades the girls to place Christmas decorations on the shrine. When Nono's grandfather sees this he tells her to leave, and that she cannot continue her training, so she stays in the mansion. Despite the harsh words, the pair miss each other's company. The grandfather relents, so Mii arranges for Nono and him to share a Christmas celebration together.

Forty years later, the girls return to the city Konami once lived in. Shortly after their arrival, Mai, the middle sister, mistakes Konami's daughter, also named Mai, for Konami. Konami's daughter has always resented being named after her mother's friend, so when Mai tries to befriend her she is at first rebuffed. Their relationship blossoms after Konami's daughter finds Mai searching through some garbage looking for the sketchbook that her classmates had hidden. The sketchbook is returned to her by some other classmates. Konami's daughter tells Mai how her mother had waited for her return, which rekindles Mai's unhappiness about the impact the girls' journey has on those who are left behind. Following Mai's sudden departure, Konami's daughter is distraught, and she suddenly realizes that her vanished new friend and the girl whose portrait her mother once drew are one and the same.
