Proof of Wife

Go to Hideout: First things first, you'll need to head down into the underground area of Lectra City. Just follow the path until you find the hideout. There will be two enemies guarding the entrance, so take them out. Once they're down, interact with the button nearby to kick off the next part of the mission.

Head to Police HQ: Now, make your way back up and head towards the Police HQ. When you get there, look for a button to the left of the main door and press it to get inside.

Free Bloodshine: Inside the HQ, you'll find a bunch of Police Bots. Clear them all out first. Once the area is safe, go to Bloodshine's cage, which should be in a corner. There's a switch on the right side of the cage – pull it to free her. Now, here's a little heads-up: as soon as she's out, Bloodshine might get a little aggressive. Just take her down quickly and grab 'Bloodshine's Mask' from her.

Place Bloodshine's Mask: With the mask in hand, head back to the Hideout. Outside, you'll see a hanging body. Place Bloodshine's Mask on it. This will open up the door to the wedding venue. Before you go in, though, you'll need to deal with Bloodshine's three friends who are guarding the entrance. Take them out.

Kill Entire Wedding Party: Now it's time to drop into the arena inside the wedding venue. You'll need to fight your way through some enemies first. Keep an eye out, because eventually, Bloodshine's Best Man will show up. He's not too tough, but make sure you're using cover and that no other enemies are bothering you while you focus on him. After you beat the Best Man, a few more enemies will spawn. Take them out, and Bloodshine's Mother will appear. Use the same tactic: stay in cover and clear the area before engaging her.

Free Naoko: Once all of Bloodshine's family members are defeated and the arena is clear, head over to the room on the left side of the arena. You'll see a cage with Naoko inside. Just shoot the lock on her cage to free her.
