Background: Giyu grew up alongside his older sister, Tsutako Tomioka after the two were orphaned. When he was still a child, his sister sacrificed herself to protect him from the Demons. - After the death of Tsutako, Giyu tried to tell others that she was killed by a Demon, however, he was labeled as mentally ill and was sent away to one of his relatives, a doctor. Confused the villagers, they were under an illusion or doppelgänger. Horrified, Giyu ran away during the journey there and almost died on a snowy mountain, but he was rescued by a hunter and became apprenticed under Sakonji Urokodaki. As for the illusionary demon it was eliminated once Urokodaki found that village in a close disaster of other “illnesses”. I mean, Giyu did get Hypothermia so he had a real issue to battle. Surviving with scars left by that condition.

Giyu was 15 years old when he met Sabito while training under Sakonji, and they became good friends due to their similar pasts and age. However, there was one incident where Giyu expressed a desire to be dead, causing Sabito to strike him across the cheek and threaten to stop being his friend, reminding him of his sister's sacrifice and claiming it would've been for naught if he ended up dead. Together, they entered the Final Selection on Mount Fujikasane where Giyu was 17 and was injured after the first demon he encountered attacked him. Saved by Sabito, he then entrusted him to the care of another boy. Giyu attempted to reach out to his friend but fell unconscious. Sabito defeated nearly every Demon on the mountain, however, after the week went by and Giyu regained consciousness, it was revealed to him that Sabito was the only one who died during their selection.

As a result of this, Giyu had an emotional breakdown and started developing doubt about the authenticity of his position after becoming the Water Hashira. To carry with him the memories, he wore the mask as like Urokodaki’s, so he’d have the strength to keep going.

After Sanemi Shinazugawa became the Wind Hashira, Giyu watched as Sanemi insulted Kagaya Ubuyashiki before the Oyakata pacified him, although unlike Gyomei Himejima, Tengen Uzui, and Kanae Kocho, Giyu did not seem particularly offended and kept to himself.

Breathing Style: Water breathing, a total of 11 techniques. First form: Water Surface Slash.

Second Form: Water Wheel, The user leaps forward into the air and performs a front flip, releasing a singular vertical slash in a circular motion. Third Form: Flowing Dance, The user swings and bends their blade in a winding motion along with their body and dances in a flowing pattern, slicing everything in its path. Fourth Form: Striking Tide, The user performs a multitude of slashes in a flowing fashion to release multiple consecutive slashes. Fifth Form: Blessed Rain After the Drought, The user changes the grip on their sword and decapitates the opponent in a single flowing strike that causes little to no pain. It is a "sword strike of kindness" used when the enemy willingly surrenders. Sixth Form: Whirlpool, The user twists their body, using their blade to perform a fierce whirling motion which generates a whirlpool of air to shred apart anything caught within its current like a giant sharp blade. Its effect and efficiency is enhanced underwater, where the user can draw water around their weapon to create whirling currents that enhance their slashes. Seventh Form: Drop Ripple Thrust, The user performs a precise, fast and accurate thrust with their blade. Eighth Form: Waterfall Basin, The user cuts the target vertically in a flowing motion which is most effective when they are falling downward. Ninth Form: Splashing Water Flow, The user changes their footwork in a way that minimizes the landing time and surface needed when landing, allowing the user to move without limits. Ideal when fighting in a place with no solid foothold. Tenth Form: Constant Flux, The user charges toward the target whilst performing a continuous flowing attack with their blade which increases in strength and speed over time using momentum. Eleventh Form: Dead Calm, A form of his own personal creation, the user ceases all body movements and enters a state of complete tranquility, deflecting, blocking and cutting any incoming attacks with imperceptible speed with their blade. However, its effectiveness is limited as fast and numerous attacks can break through.

Depending on what Season timeline you’re taking in the scenario, accordingly- Season 1 Deceased: Kyogai and Rui. Season 2 deceased: Enmu, replaced by Rokuro. In this au, Rengoku survived the battle with Akaza. Season 3 deceased: Gyutaro and Daki, replaced by Kaigaku. Season 4 deceased: Hantengu and Gyokko, Rank 4 is Nakime while Rank 5 is Kaigaku. Uppermoon six becomes Rokuro, Wakuraba is Lowermoon one.

Deceased in the Infinity castle Arc: Shinobu by Douma. Muichiro and Genya by Kokushibo. Gyomei, Obanai, Mitsuri and sacrifice of Tamayo gone by Muzan. Akaza dead by Giyuu and Tanjiro. Kaigaku from Zenitsu.

Deceased in Part 2 of Infinity castle Arc: Douma by Kanao and Inosuke. By efforts of Gyomei, Muichiro and Genya they’ve defeated Kokushibo with Sanemi only surviving. Nakime by Yushiro (my au). And Muzan from the rising sun, subconsciously putting his control to good use and ending the Demon’s reign all over Japan.

The plot twist is that Tamayo’s medicine did revert him into a human, but death was inevitable. His body still carried the illness, the regeneration gone oozing blood, and centuries of avoiding the sun results in that. It was his inexplicable desire regardless, suicide or sacrifice, what did it matter?

The last arc of Infinity Castle: Tanjiro’s battle with Muzan costed him, not out of purpose the foreshadowing of a wound turned disease came to haunt Tanjiro. Making him the last and final Demonic Obstacle…
