Our Family in Summer

This is the sequel to the animated movie, 'Summer Wars'. It is very underrated, and it deserves so much more credit. It has been with me since a toddler, and I have always enjoyed it. If you haven't watched it, I advise you don't continue pass this point, because of spoilers. Anyways, this story is about Koiso Kenji, returning to the Jinnouchi House, exactly a year after the OZ incident. Many things have changed from back then, but Kenji did not expect one thing that happened on his second morning of his stay. Everyone's OZ characters were jumping out of their screens and begging for help. When Natsuki, Kenji, and Kazma's characters had appeared, they explained that there was a new threat to their world, and it was up to them to stop it. What happened, and will the simple Jinnouchi Family be able to stop the threat?
