Fishing in the Haunted Sea: I Haul Up Cthulhu from the Start

In the modern world, Song Wu is a young man obsessed with fishing. While fishing far out at sea one day, a whirlpool suddenly rises from the calm waters, and a tremendous force seizes his line. Song Wu summons all his strength and reels in a gigantic, terrifying Cthulhu from beneath the waves. Cthulhu fixes its glowing eyes on him and somehow conveys its submission through telepathy. It has sensed the special aura hidden within Song Wu. Stunned, Song Wu accepts Cthulhu as his mount.
