She Went and Entered It (入っちゃったじゃんよ Haitchatta jan yo?) is the hundred thirty-fifth chapter of the Dandadan manga series.
Summary[]
After being sent falling inside the diorama, Momo finds herself landing in a land made up of desserts. A scroll then appears in front of her that welcomes her to the diorama known as Danmanra and receives a card with a diagram, which she fails to understand. Momo proceeds to explore the land and comes across an entrance with a set of weapons. Momo recognizes the swords as the same ones the old man used and takes one of them for herself. As she wonders if there were any monsters as the old man had said, Momo finds that the ground is made up of cream, looks in front of her to see a hill, and sees a scroll appearing that reads National Border Hill. At the gang's base, gang members prepare to have the old man sent inside the diorama but is stopped by Okarun who notices that a figurine of Momo is inside. A gang member tells Okarun that a figurine of Unji was inside the diorama to but was out of sight a few days ago, which they figured was a sign that he was in danger. Both Okarun and Momo then come to the realization that the diorama is actually a game.
