As they all say, all good things come to the end. Kobato uses her remaining time to make Fujimoto happy by taking him to the park and stuff. They even went on a boat ride and Kobato couldn’t even row the boat correctly, which is the funny part. However the second part gets a hell alot more serious She says farewell to the landlord, Chitose and Kobato and Ioryogi leaves to the place where she first arrived. Fujimoto comes home and finds out that Kobato left and he looked everywhere to find him. After Kobato failing to fill the bottle, Fujimoto came and finds out that Kobato is actually dead all along and needed to fill the bottle so that she would reborn or revived in the world. After Fujimoto shattered the wall, the last Konpieto came, but after it filled, the contract cannot be changed and Kobato disappears along with Ushagi.
I swear, Ushagi is one mean bunny… or rather, nightmare fuel. I bet after the viewer saw what Ushagi did, well, I guess viewers are going to gain an irrational fear of bunnies now because they will giggle that makes you disappear in your dream and gold a freaking flower and do bad stuff. As Ioryogi said, you cannot change her fate at all… and that you are stuck what you have… unless you have a Deus ex machina. I think it was too late for Fujimoto to show his true feelings towards the end… and well, we don’t know how it will turn out until the next Episode… so stay tuned…
