That Kawabanga Girl (カワバンガというやつは Kawabanga to Iu Yatsu wa?) is the hundred fifty-eighth chapter of the Dandadan manga series.
Summary[]
Turbo Granny instructs Rin to carefully place the cursed trunk on the black cloth, enabling her to handle the trunk and extract the figurines without harm, and to proceed with caution, as even the smallest crack to a figurine could be fatal. With the bench the cursed trunk is sitting on fixed to the ground, the young girl, once dispatched to Danmanra, attempts to move the cursed trunk using sticks. However, this plan backfires as she ends up sent back to the inner world, with the Turbo Granny warning Rin too late that such an attempt would be ineffective. Seeing as how Mai is a yokai who has a resistance to curses, the Turbo Granny instructs Rin to have Mai use the black cords they brought with them to slip them around the cursed trunk and carefully lift it to the black cloth. However, Mai declines to work with Turbo Granny and insists that Rin should be the one to rescue them. She then fuses with Rin as a revealing idol outfit, much to the latter's embarrassment, and encourages everyone nearby to cheer for Rin to give her the strength as she sings.
Meanwhile, everyone notices that the world of Danmanra is starting to fall apart, much to the Turbo Granny's panic since this will result in everyone being erased as well. In the midst of this, everyone suddenly finds themselves being lifted up into the air, with the exception of Momo who grabs onto Okarun's hand. After noticing a song being sung, the Turbo Granny figures out that the cause of this phenomenon is the Onbusuman's power over gravity, which is being used by Rin to levitate the figurines out of the diorama.
