Idle Death Gamble

Idle Death Gamble is a domain expansion used by Kinji Hakari.

Introduction
Idle Death Gamble: CR Private Pure Love Train Version 1/239 is based on a real pachinko machine and gets its theme from the eponymously named romance manga series. The user's goal is to hit the jackpot by lining up three of the same symbols decorated with the characters of Private Pure Love Train. The jackpot bonus grants the user unlimited cursed energy and a fully automatic reverse cursed technique for four minutes and eleven seconds, the duration of the Private Pure Love Train theme song, "Admiring You".

The user must participate in the flow of the game in order to hit the aforementioned jackpot, with only a one in two-hundred and thirty-nine chance of doing so. All the rules of the game are transferred into the opponent's brain through the domain's sure-hit effect. This process is harmless, and as a trade-off, the construction and cursed technique infusion of this domain are extremely fast, activating in less than 0.2 seconds. This also makes Idle Death Gamble very effective in a clash of domains.

Game Flow
The game begins in normal mode, where those inside appear on a neutral stage. As the battle begins, the user can manifest three different types of visual effect indicators in battle: shutter doors, reserve balls, and consecutive effects. Conjuring doors and balls are offensive attacks, but consecutive effects are defensive indicators that redo a sequence to revert damage. Doors and reserve balls come in a green, red, or gold rarity to symbolize a higher chance at a jackpot. Rainbow-colored indicators or four re-doing four consecutive effects guarantees a jackpot. The user can choose which visual indicator to manifest, but their success is up to luck. Generating one or more visual indicators progresses the stage to a riichi scenario and reveals two of three of the numbers needed for a jackpot.

There are four riichi scenarios with different chances of hitting a jackpot, with the final train riichi having over an eighty percent chance. Each of the scenarios changes the stage and uses the characters of Private Pure Love Train in a different way. For example, the transit card riichi scenario takes the user and their opponent to a different part of the train station where Yuki must pass through the gate and get to work on time to hit the jackpot. This is a low-chance scenario and is likely to fail without rare visual indicators. The user's opponent cannot obstruct the visualization of the riichi scenarios and must watch it unfold or defeat the caster before it ends.

Jackpot Bonuses
Failure to hit a jackpot within a scenario will revert the stage back to the start. This will repeat until the user wins or runs out of chances to do so, with the number of possible spins decreasing with every missed jackpot. On the first activation of consecutive expansions, the probability of hitting the jackpot is over twenty percent.

If a jackpot is hit, the domain disappears, and Admiring You plays out loud around the user, who receives a bonus of unlimited cursed energy for the duration of the song. The user has no restrictions on cursed energy and can receive bonus amounts randomly throughout the round. The unlimited cursed energy causes the body to reflexively heal itself even if the user never learned to perform reverse cursed technique. This prevents the user's body from retaining damage and makes them effectively unkillable for four minutes and eleven seconds.

By the end of the song, the user's cursed energy recedes back to normal and their cursed technique has already been replenished. This allows them to open their domain repeatedly as long as a jackpot is achieved. The conditions of the game carry over from consecutive uses as well. If the user lined up three odd numbers, the stage will open in advanced probability rather than the neutral state. If the user lined up even numbers, they will start on a stage with faster spins. There is also a chance for the stage to begin in hidden probability, a pachinko mode similar to faster spins but actually carries an increased probability to hit the jackpot.

Usage
Hakari's cursed technique is mainly employed through Idle Death Gamble. His fighting style and tactics revolve around using his domain to hit the jackpot and defeat his opponent using the bonus of unlimited cursed energy. Hakari first displayed his full power when he thoroughly crushed Charles Bernard's violent tendencies. Hakari used Idle Death Gamble in their fight in the Tokyo No. 2 Colony. Charles was instantly appraised of the domain's rules and he immediately expressed that the massive dump of information irritated him.

Aware of the rules of the game, Charles attempted to follow its flow while fighting Hakari. He took note of the green reserve ball and green shutter doors Hakari first attacked with. Charles recognized them as indicators and knew that activating riichi mode would follow. Hakari chanted riichi as he punched Charles and spun two number four symbols. Advancing to the next stage, both fighters entered the low-chance transit card riichi. Charles was unable to interact with the visualizations and his G Warstaff couldn't predict the indicators or the outcome of the scenario. Hakari ultimately failed to hit the jackpot by drawing a five instead of another four, returning both fighters to the starting stage. Charles quickly realized that this would continue until one party lost. Despite avoiding a jackpot in the first go, Charles was upset that Idle Death Gambe: Private Pure Love Train Version 1/239 appropriated the manga by Candy Nakamura of the same name.

Hakari conjured gold doors to defend himself from Charles before entering the next scenario. Charles recognized this indicated a high chance for a jackpot. While activating riichi mode and spinning two number three symbols, Hakari boasted that he never needed more than thirty spins to hit a jackpot. They advanced to the high-chance final train riichi and it initially appeared as if Yume departed on the train, which would not have resulted in a jackpot. Charles assumed this was the case and was able to channel his relief into focus, injuring Hakari. However, the visualization revealed that Yume missed the train as she reappears next to Yuki. Hakari spun three number three symbols in a row and used his bonus cursed energy to defeat him with a single kick.

Hakari rescued Panda from Hajime Kashimo during the bonus round after hitting the jackpot against Charles. Kashimo sensed Hakari's overflowing cursed energy as the latter made his dramatic entrance. Hakari's increased durability allowed him to land on top of a metal shipping container and completely crushed it without injuring himself. He followed up with a punch that sent Kashimo flying through another freight container. His overwhelming cursed energy output also allowed Hakari to completely ignore Kashimo's electrification. Normally someone would suffer an electric shock from hitting Kashimo but Hakari barely felt a tingle.

Shortly after their opening exchange, Hakari received a bonus of cursed energy that further empowered him. Kashimo landed several undefended hits but Hakari was able to take them without suffering significant damage and immediately counterattacked. After having his arm severed by Kashimo's lightning, Hakari was able to keep fighting because he knew his arm would automatically heal. The round ended directly after Hakari's arm recovered and Kashimo noticed the music ending alongside the recession of his opponent's cursed energy. With his cursed energy returned to normal and his cursed technique replenished during the round, Hakari immediately expanded his domain again, something he's capable of doing repeatedly as long as he continues to hit the jackpot.

Kashimo was already intrigued by Hakari's unique abilities and gaining information on how they worked allowed him to better analyze his opponent. The domain apprised Kashimo of its rules faster than he could give up defending himself with Hollow Wicker Basket. Since Hakari lined up three odd numbers against Charles, this time the game began in increase probability mode. Kashimo recognized that Hakari was likely to keep hitting the jackpot but was also aware his opponent wasn't unkillable while in the domain. Hakari's base state was easily outdueled by Kashimo's superior physical prowess but he used the consecutive effect indicator to replay brutal exchanges and undo any damage he took. The risk of failing to activate a consecutive effect is greater upon the second activation of the domain so normally Hakari would avoid it unless he has increased probability. He used consecutive effects twice in a row and to avoid lasting damage from Kashimo and then went right into riichi mode, drawing two sixes. Hakari and Kashimo entered the potty emergency riichi and even worked together to interact with the visualization, ultimately resulting in a jackpot. The music began after the domain was dispelled and Kashimo recognized that Hakari returned to his unkillable state, with no restrictions on cursed energy and a fully automatic reverse cursed technique. He also noted that since Hakari hit a jackpot using even numbers, the increased probability wouldn't be in effect for the next expansion.

During the succeeding round, Hakari's automatic reverse curse technique healed several injuries to his head, including a direct hit from Kashimo's lightning. Hakari survived by expelling his opponent's cursed energy through his nose while his brain healed itself. With eight seconds left in the round, Hakari's physical prowess increased and he overwhelmed Kashimo with a reckless assault. Just as the round ended, Kashimo hit Hakari with another unexpected bolt of lightning he was unable to heal from. Despite suffering a fatal wound, Hakari used the last of his strength to expand Idle Death Gamble once more.

Hakari successfully cast his domain but Kashimo assumed this attempt was in vain and that they would enter a mode with faster spins and not increased probability. With only a one in two hundred and thirty-nine chance of hitting the jackpot, it was likely Hakari would fail to do so and die. However, on the very first spin, Hakari lined up three number-two symbols and hit the jackpot due to hidden probability, instantly healing himself.

Kashimo's next attempt to overcome Hakari's auto-healing was poisoning him with chlorine gas. Nullifying toxins requires an advanced reverse cursed technique, which Hakari's unkillable mode is able to achieve unconsciously. With only five seconds left in the round, Hakari decided to try and defeat Kashimo rather than distance himself to cast the domain again. Kashimo was aware Hakari was headed for increased probability mode if he expanded Idle Death Gamble again, so he attempt to kill Hakari with a steam explosion that would at the very least destroy his arm and prevent him from using hand signs to cast the domain.
