Preheat oven to 400°F (200°C). Cut kani sticks into 2 or 3 pieces and place in mixing container. Mince half of the shrimp finely and roughly chop the remainder to create textural variation. Slice scallops into smaller pieces if too large. Add cream cheese (or extra spicy mayo) and a spoonful of spicy mayo sauce. Optionally add a few drops of lemon juice for brightness. Use a fork to mix while breaking kani sticks into thin strips. Spread additional spicy mayo evenly across the top surface.

Bake the seafood mixture for 12-15 minutes until bubbling and shrimp are fully cooked.

Place a sheet of nori shiny side down on a bamboo rolling mat. Spread seasoned sushi rice evenly across the nori, applying gentle pressure with fingertips. Arrange kani and cucumber strips (or preferred fillings) along the center. Lift the mat and roll while applying gentle pressure to form a tight cylinder. Cover with plastic wrap and set aside. Repeat for additional rolls if needed.

Slice each sushi roll into 10-12 thinner pieces rather than standard 8 to accommodate the added height from the topping. Arrange slices on serving plates. Carefully spoon the baked lava seafood mixture onto each slice. Drizzle with additional spicy mayo and unagi sauce. Garnish with masago or dots of Sriracha for extra spiciness. Serve immediately without additional soy sauce as the flavor profile is already well-balanced.
