Hi my name is Ekko and I’m a time traveler. I lost most of my memories because of an accident, but fragments of memories from different lives rushed into my brain. Under the stimulation of these memories with my head, I have the ability to travel through the time. Every time, just my soul not my body, I travel to a person with different time period, different backgrounds and different gender, but I can only travel through a week. All I want to do is collecting all my different experiences to get back my lost current memories. Through every time travel, I will see the different world from different lives.
