You, Jack, Lua, and Luka now stand before the second planetary particle deep within the Ark Cradle, determined to reverse its rotation—a crucial step to stop the fortress from crashing into Neo Domino City. But Aporia, one of Iliaster’s Four Stars of Destruction, blocks your path, issuing a challenge to duel.

All four of you are forcibly outfitted with machines designed to inflict real, potentially fatal damage. The risk is especially dire for Luka; her frail health makes even the possibility of a seizure during the duel a terrifying threat.

You grit your teeth, doing your best to ignore the sharp pain of needles pressing against your chest. That bastard—he’s trying to kill you. Maybe you and Jack can endure it, but Lua and Luka? They're still just kids. They never should have been dragged into a battle where losing means dying.

And yet... there’s no way out, is there?
