Tidemaw Tidemaw is the largest kaiju ever recorded: a Class 5 Leviathan, 80 meters tall and 24,000 tons, plated in oily black-blue chitin and lit from inside with pale green. Every other kaiju walks out of the bay. Tidemaw brings the bay with it. Wherever it goes, the tide follows it inland, and the city drowns behind it. The night the sea came in No kaiju had ever flooded Haeseong before. When Tidemaw rose, the water rose with it, up over the sea wall, through the Port and deep into the Tide Wards, filling streets to the second floor. Thirty-one people died that night, the worst loss since the First Tide, and more than forty thousand lost their homes. By morning the water had gone back to the sea and left a brown line on every building it touched. The line is still there on most of them. What it is Tidemaw is twice Brinemaw's height and roughly eight times its mass. It has four primary limbs ending in hooked claws built for tearing open ship hulls, and a second, smaller set of arms folded against its chest for holding what it catches. Its hammerhead skull is split by a vertical maw of teeth that glow green from within. A dorsal fin array runs the length of its spine and crackles with stored electricity, and a thick whip-tail sweeps anything behind it flat. It doesn't roar often. It saves that for impact. And it is intelligent in a way nothing before it was. When a mech wounds it, Tidemaw remembers that mech, and goes for it first. How it fights Slowly, and without stopping. Tidemaw doesn't charge or chase. It walks, and the water comes with it, so every fight against it gets deeper the longer it lasts. Streets become canals. Mechs lose their footing. Anything that falls goes under. It drags the fight wherever it wants to go, and it always wants to go inland. Up close it tears. Those claws were made for hulls, and mech armor is thinner than a hull. It can throw a 20-meter mech through a building. It can hold one under. Weak points The maw. Only when it opens, and only for a moment. The underbelly. Between the chitin plates, where the armor is thinnest. Old wounds. Tidemaw remembers who hurt it, but it can't grow the wound closed in the middle of a fight.

The flood in Rin's fight with Brinemaw was never Brinemaw. The first surge that came over the sea wall that night, and killed people in the low streets, was Tidemaw rising underneath. Everyone blamed the wrong kaiju. It is the hardest fight TIDEWALL has ever had. The fight starts in the bay and Tidemaw drags it inland, through the low wards and between the towers. It throws a mech through a building. It slams White Petal down into the floodwater and Aya's cockpit fills with alarms. In the end Nari wraps Crimson Howl in her field and amplifies it, Miko pours everything she has into one shot that blasts Tidemaw's weak point open, and Rin and Aya go in with the blades. Tidemaw falls into its own flood. The lightning dies, and the water goes still. "It's over," Rin says. Then why doesn't it feel over? Because the sonar kept climbing after Tidemaw fell. Whatever it caught past Class 5 was never Tidemaw. Tidemaw wasn't attacking Haeseong. Like every kaiju since the First Tide, it was running from Ommoros's slow rise toward the light, and Haeseong was simply in the way up.
