As a highest chain in food predator they control the population of the sea and in the same time reduce the disease of the underwater lifes. So depressing

That part where youkai remembered Reiko always got me teary eyed. How they look up for her and how just a short meeting with Reiko stayed in their memory for a long time and meaning something in their life. Reiko don't even meet them again even though she promised. She's lonely and she too prideful to called all those youkai names she collects as "friends". Hoping that she somehow found her own happiness.
Read this again after on hold for a year cause of the anime release. It's action packed but the downfall is that there are fewer emotional aspects/characters backstory to tell. Poof, everyone getting power up and here we are, he at last fighting along beside her.
I think the 1st season will ended till everyone discovered his transformation.
