   Summary

   Sanemi loved the ocean since he was kid - he always dreamed of taking a boat and going far, far out, exploring the depths of the sea, finding a brand new species. Naturally, he loved his job.

   Out on an ordinary Monday to simply complete his tasks and record some fish, he makes a discovery far beyond his own comprehension - a curious, lone siren had been following and watching his boat for weeks, waiting for a chance to finally make contact. In pursuit of this creature, Sanemi finds himself stumbling deep into an unpredictable whirlwind of unforeseeable calamities and complicated feelings.
