The battle began as Link tried to take several leaps backwards, the water slowing her actions and she was forced to try to swim around while clutching her sword and shield. She instantly knew this wasn't going to do for a fight. Link put her weapons away and drew out her hookshot, one hand aiming the thing cautiously at the Angler Monster's dangling temptation, her other hand managing to pull her bottoms up enough she wouldn't trip over them.
The orb rushed forward, and Link rolled to the side, easily avoiding the creature's charge, but her hookshot launch in retaliation clanked uselessly against the rocky wall of the cave. It was hard to target that illusion orb, the monstrosity moving it anytime Link's attack was launched.
The beast tried to rush Link again and a second shot was timed perfectly, the creature's Ruto figure snapped against with the hookshot, and its enormous teeth appearing a second later, about to bite into Link, a fast side-hop and a brisk sword strike had it roaring in pain as it slammed into the far wall, rocks dropping from the ceiling.
Huge rocks slammed all around Link, blocking off her view and making it harder to keep track of the Ruto-copy that spun round and took up the offensive again. The figure disappearing behind one rock and peering tauntingly around the side, rubbing her breasts and moaning like a common whore, "MMh, you know you want some of this. Just give in..."
Link felt the waves of magic eminating off of the creature, and she knew how it was copying Ruto's form. Her hookshot aimed, and fired, the creature's spell felt the strike full on, and the hookshot snapped... Link yanked back and felt herself hurtling towards the thing, one hand on her sword and slashing through the formerly glowing orb, as a huge amount of blood spurt forth from the monster's cleaved body, the fake image of Ruto screaming out in protest as it faded, falling to the ground, its glow slowly disappearing, and Link saw it was nothing more han a shimmering sphere with many tendrils hanging off of it that it controlled to create a fake body.
Foul tasting blood was quickly filling the cave, and Link felt ill just to be in this water, needing to breathe it only made the feeling worse, her hookshot drawn, she looked around as the fish slammed into the far cave walls, without its tiny light, the monster seemed unable to navigate or see in the darkness anymore. Huge bangs and crashes were heard all around her as the monster flailed violently, and even more rocks started to fall from the ceiling, crashing down against Link and she felt one of the huge rocks pin her down, as small beams of light came down from the cracking ceiling.
"You think you've hurt me, but I'll regrow that in a week... Let's see if you can regrow the flesh I chew off of your bones..."
The creature smashed down near Link and she felt the earth dragged up around her, and vicious teeth sinking into her body, sending waves of pain through her as the creature caught her, legs in its mouth and her upper body flailing free from it, until the monster slammed into a far wall again, Link's body slammed hard into the wall, but freed as she sank back to the hard ground beneath her, the bloody water thick around her, and she felt horribly ill, swimming hard to try to get away from the sickening taint of the blood.
The entire cave finally collapsed around her, Link barely escaping being hit by more falling rocks as she collapsed just outside of the cave, puking her guts out after being in the foul water so long. Her entire body was trembling, she could barely hold her sword and hookshot when her mind rejoined the battle, looking upwards, she gasped out, eyes wide and jaw dropping...
All around the cave was a swarm of Biri, hundreds, perhaps thousands of the creatures, so many that she couldn't see through the mass of them up to the surface of the water overhead, they blocked out anything she could see. The Angler Monster was gone from sight, only these tentacled electric beasts were visible, completely surrounding her.
Link heard a resounding screech, and before she could react, the enormous angler creature burst through the wall of biri and slammed into Link, she barely brought her sword back in time to slice at its jaw and free herself before it slammed its fangs down, slicing at her leg, but she quickly found herself tumbling and tossed, the beast was enormous, and could've swallowed her whole without even trying if she let her guard down.
She hit the ground hard after being tossed through the waves helplessly, blood coming from her stomach and leg, her vision was dimming. After several hard blows, her outfit bottoms were torn, only hanging onto herself because they caught on her belt, and her top was sliced up from those teeth, leaving her essentially nude, but thankfully the magic of the outfit still holding.
She could tell that the enormous monster was injured, but not badly enough that this fight was going to end in her favor at this rate.
The beast rushed her again and Link screamed out as its powerful body slammed through her, sending her hurtling backwards, her body spun and flung about again, and one of the biri that had caught the Angler Monster came loose as it tumbled into Link, sending both of them spinning to the ground, the familiar feeling of tentacles all over her body making Link worry that this would be the end, her breasts and pussy stroked, the thing holding her tighly...
No shocking came though, only a light crackling through her body as Link looked over the creature cautiously... something seemed familiar about it... Link realizes suddenly that this was the very biri that had impregnated her with its eggs.
Still in a panic, Link spots the Angler coming after her again, leaping out of the way and launching her hookshot, snapping it against the thing's side and she feels herself yanked onto the creature's side, she barely manages to hang on as it bursts through the swarm of biri again.
Link then understood why the biri were swarming, dozens of the things trying to grab on to the angler, shocking at it, attacking it, but it kept shrugging them off of its tough scales.
Her grip slipping as the beast twisted and sped up, Link fell to the ground again, skidding to a stop next to a few pieces of sea weed, spotting one of the sensors that were dropped earlier nearby, and that biri still clinging to her body harmlessly, seeming to want something from her, Link's entire body aching and she knew she couldn't keep this up much longer. She glanced up and found a single ship floating nearby, but its size instantly told her it was the hunters, obviously come looking when they spotted the swarms of biri, but they didn't seem aware of the larger prey nearby.
She had only a moment to react before the thing rounded for a final attack. Link quietly knowing this would be the end...
... one way or another.
