From Yuri Project:
In her dreams, Chika can freely confess her love for Mitsuki. But the reality, where she barely manages to talk properly with her classmate, isn’t as kind.

Every day in Japan, 2500 people die due to any number of causes. Do you think you'll be one of the ones to die? No, of course not. Do you think you'll win the lottery? You'd like to think so, we all would. But Sumida is different. He wants the status quo to remain in every way; live a normal life, get a normal job, have normal kids, never to be anyone fortunate or unfortunate, content in normalcy. Anyone who doesn't agree is foolish, doomed to live their life scraping up a mountain that they can never conquer, fated to die in despair wishing things had been better.

When his mother kicks his father out of the house and onto the streets, he thinks he'll be fine. When his mother leaves him to live with her boyfriend, he makes the best of it. When he realizes that he's no longer average, he strives to make his life worthwhile the only way he knows how. When the demons in the back of his mind speak to him, he tries his best to ignore them.

It's a desperate struggle of survival on a deserted island between this woman and the different groups of men who are pitted against her, some of whom might turn out to be allies.

A couple of decades have passed since Ultraman last was seen in Tokyo, and his kaiju nemeses seem to have gone back into outer space. Former Ultraman Shin Hayata has forgotten that he ever wore the metal suit, though as Minister of Defense he still takes a keen interest in protecting Japan. His young son Shinjiro knows that his dad once worked with the SSSP (Science Special Search Party), but not that that explains how he came to have amazing strength and other seemingly supernatural abilities; as a moody teen he just thinks they make him weird. But then one day a dangerous alien comes back to Earth, and everything starts to become clear. Will Shinjiro don the suit and become the new Ultraman?

She's really a mouse...but he thinks she's a tiger!
