With a powerless ASV suit, Daisuke is at a distinct disadvantage against a seasoned bodyguard in Frantz Weinski armed with a mini-railgun-like weapon. Then Daisuke spots Haru in the shadows and has him drop a shipping container about as close to Frantz as possible without crushing him. Even after Haru saves him and patches him up in the galley, Daisuke still thinks Haru should have killed the guy, but Haru is a civil servant, not a secret agent, i.e. no license to kill, even in international waters.
Suzue isn’t sleeping on the situation, as she launches an armada of drones at the ship. They’re all shot down by lasers, but out of their wreckage emerge even smaller drones, one of which makes it to Daisuke with a new earring. Now no longer blind or on his own, Daisuke has Suzue map out the route to the engine room, where the Allodium reactor itself is interfering with his ASV suit.
Daisuke is somewhat slowed by his wound, but he still insists Haru go topside to serve as a diversion while he goes to the engine room alone. This means Haru has to run around and attract the attention of Frantz and the guards but not let them get close enough to kill him. Ultimately Frantz sees what Haru is doing, then races to the engine room to give Daisuke the “lesson” Shigemaru paid him for.
Haru isn’t far behind, and he has his gun…he just can’t shoot it. Not until Daisuke, remembering what Hoshino said and all the adventures they’ve been on, tells Haru that his job is to “make justice happen!” A simple civil servant won’t do in this situation…a hero is what’s needed. Haru’s hand steadies and he shoots the right wire that interrupts the cooling system and shuts down the drive.
With the drive down, Daisuke’s ASV is back online, which means he can be the superhero and incapacitate Frantz with ease. Then the drive blows and the ship starts to sink, so Suzue sends a chopper to rescue them. Daisuke heads to the bridge first, and Haru follows him.
There they find his dad, who has nothing to say for himself. Rather than take care of “family business” his own way, Daisuke holds out handcuffs for Shigemaru to take. He may have tossed his badge earlier, but still he intends to make justice happen, not revenge.
Unfortunately, Shigemaru gives them the slip, using HEUSC to fire a laser at Daisuke and then escaping on a hoverbike. But rather than chase him, the two detectives first do their jobs, loading Frantz and the crew members onto the chopper and taking them back to shore.
Only when their captives are safe do Daisuke and Haru head back to the chopper. When Hoshion asks Haru where they’re headed, Haru tells him, with a smile and glint in his eye that the final boss still needs to be caught. Hoshino grins at that; thanks to Daisuke, the hero is back.
