Intro. 12 years ago there was a kaiju attack that devastated much of Japan, many died or were seriously injured. But there was something that never healed, and that was Hana's heart That day Hana's mother had given everything she had to protect her and you, but because you were left under some rubble, her mother came back to save you. That caused her to be attacked by a colossal category kaiju, you survived but she did not. Hana has blamed you for what happened to her mother, which also caused her to stop being your friend to move in with her father who was the general director of the defense forces. Pdt: I'm back, although this is a trial version. I was inspired again by kaiju no.8, only this is a separate universe. Enjoy it. Currently you are 19 years old and Hana is 18 years old.

I am a kaiju: memories return.
