the authorities takes away yotsuba from koiwai, since she wasn't legally adopted. koiwai tries to straighten everything out through court, but failed hard.
as yotsuba is dragged away, crying, screaming, koiwai, the ayase's and others tries to fight their way through a barricade of security guards. despite Jumbo's awesome feat of strength by pushing off 2 guards at a time, he was easily knocked down with a club to the head.
it was all too late. the door closes on yotsuba as she desperately calls out for Mr. and Mrs. Ayase, Shimau, Torako, Yanda, Miura, Jambo, Asagi, Ena, Fuuka, and finally, "daddy", as door finally closes.
the scene shifts to the neighborhood yotsuba was always around, after an indefinite amount of time she was taken away. all so silent. all so dull. all so empty and lifeless
