... Come to think of it, even our own existences are mysterious....Miss Tenryuu...Such as how I used to have someone important to me...Yet, I can hardly remember her face or her voice... But I know she's there, inside my memories...Like Jun'you said... not all of our memories are things we would want to remember, so it'd be best to leave them forgotten.So if possible, I would like to remember about her...For example, it would be really bad if you suddenly remembered the time when you were an Abyssal Ship.Surely you wouldn't want to remember something like that, right?Abyssal ships were there first, then they die and gave birth to Ship girls, who in turn turned back to antagonize the Abyssals...
