Seikai Suru Kado is a continuation of Rakuen Tsuihou: Expelled from Paradise.

Koujirou Shindou is a brilliant negotiation official working within the Ministry of Foreign Affairs.

He finds himself at Haneda Airport waiting the plane he has boarded to finish preparations for takeoff, when all of a sudden, a mysterious and enormous cube appears in the sky. The ‘cube’ rapidly expands and all 252 passengers aboard this aircraft are all sucked into the cube. The cube is called ‘Kado’. Once inside of ‘Kado’, a strange creature appears and YAHA-KUI ZASHUNINA. YAHA-KUI is attempting to make contact with humanity. Suddenly, Shindou, who himself has been sucked into ‘Kado’, now finds himself forced to be the mediator between YAHA-KUI and humanity. Meanwhile on the outside, the official representative of the Japanese Government and International Negotiations Officer, Saraka Tsukai, is dispatched to the location as well. What and who exactly is YAHA-KUI ZASHUNINA? And what is he after?

Upon watching this anime for the first time, I thought it was going to be boring, as the plot seemed to be a bit slow at first. But as I continued on to episode 2 and 3, things started to pick up, and that’s where it gets interesting. The plot really kicks off when an outer space cube, possibly alien, suddenly makes its appearance on Earth. In the midst of all that, a plane was caught inside the cube along with Kojirou Shindou and the rest of the passengers. With expert negotiation skills, Kojirou Shindou negotiates with Yaha-kui zaShunina to ensure the passengers safety and well-being, as well as with the government of Japan. Will he able to bring peace and establish an alliance with this mysterious creature?

The only thing that bothered me with this anime is how it was animated. You can see there is CG animation involved and it became a turn-off for me at least, since it made the scenes look so… square? Other than that, it’s an interesting anime to watch.
