Homusubi

Homusubi is the released form of Akira Izanagi's sword, Shuiro.

Design
Homusubi is a very simple weapon. Like its previous form, Homusubi is a Chokuto, a straight-edged katana-like sword. However, it becomes an extremely simple in design. Its blade is wreathed in compressed flames, turning it white-hot with a rainbow-like effect across its surface. It lacks a handguard, and the samegawa that previously covered its hilt is missing, revealing the folded metal around the blade's tang acting as the handle. The Weapon Release state also affects the user's appearance, wreathing the user in compressed flames. The fire covers the user's forearms, shoulders, chest, and their coattails if applicable. All of this fire changes color depending on what flames Akira is channeling.

Abilities
Homusubi is a sword surrounded in fire. As an Elemental Release, Homusubi holds incredible control over Fire; more specifically, Akira's signature Chromatic Flames. The flames are so tightly compact, the sword does not emit smoke or visible flames of any kind. In its default state, Homusubi simply glows white hot, with a rainbow gradient across the blade's surface. Due to its tight-knit nature with Akira's Chromatic Flames, Homusubi is capable of channeling each individual flame across its blade and user, changing the user's physical attributes to an extent in tandem to the nature of the chosen flame. Known as Chromatic Ashes, these different colored states can be accessed by carving the Kanji of their names into the air, creating a trail of flames in the shape of the Katakana, and slashing through these flames. By doing so, the flames covering his sword and body will change to that specific flame's color and attributes. They are as follows:
 * Homusubi: Sakura (火産霊: 桜 Homusubi: Sakura) - Homusubi's Sakura Chromatic Ash is strange. While initially accessed by activating Weapon Release, this version is rather weak in comparison to other Chromatic Ash states. The flames burn white hot, though there is a slight tinge of red that dyes the flames in a color reminiscent of Sakura leaves.
 * Homusubi: Seven-fold Sakura (火産霊: 七つの桜 Homusubi: Nanatsu no Sakura) - After cycling through the other 7 Chromatic Ashes, it can be accessed again by carving the number 7 and the kanji 桜. Returning to the Sakura Ash after using the other Ashes allow it to blend all of the other Ashes' attributes together, allowing it to wield the different attributes while maintaining its red-tinged white flames. This Seven-fold Sakura state is extremely difficult to achieve, as cycling from one Chromatic Ash to another is already an Aera-taxing process, and this enhanced state consumes even more Aera than other Ashes. If successfully achieved, Akira's combat prowess increases seven-fold from his other Ashes.
 * Homusubi: Crimson (火産霊: 真紅 Homusubi: Shinku) - Accessed by carving the kanji 真紅, Homusubi's flames transform into a deep crimson. All of its attacks burn much hotter and deal more damage with each swing, at the cost of greater Aera consumption.
 * Homusubi: Amber (火産霊: 琥珀 Homusubi: Kohaku) - Accessed by carving the kanji 琥珀, Homusubi's flames transform into a bright orange. Akira almost always switches to this Ash state, using it as his default combat state due to its balanced combat parameters.
 * Homusubi: Gamboge (火産霊: 藤黄 Homusubi: Tōō) - Accessed by carving the kanji 藤黄, Homusubi's flames transform into a shade of yellow reminiscent of Buddhist Monk robes. These flames are reinforced with light, enhancing defensive capabilities and durability at the cost of greater Aera consumption.
 * Homusubi: Bamboo (火産霊: 青竹 Homusubi: Aotake) - Accessed by carving the kanji 青竹, Homusubi's flames transform into bamboo green. Speed and agility increase significantly, allowing the user to dash around the area and blitz the enemy with high-speed strikes.
 * Homusubi: Lapis (火産霊: 瑠璃 Homusubi: Ruri) - Accessed by carving the kanji 瑠璃, Homusubi's flames transform into a beautiful blue. These flames burn in a more passive manner, providing a tranquilizing effect and lowering collateral damage to the user's surroundings
 * Homusubi: Indigo (火産霊: 二藍 Homusubi: Futaai) - Accessed by carving the kanji 二藍, Homusubi's flames transform into wispy indigo. The volatility of these flames cause random explosions while accessing this Ash state, though Akira can control and unleash these explosive flames through Homusubi's blade or his hands. The random explosions do harm him, though they are often small-scale.
 * Homusubi: Plum (火産霊: 梅紫 Homusubi: Umemurasaki) - Accessed by carving the kanji 梅紫, Homusubi's flames transform into plum-like purple. These flames are among the most dangerous, as this Ash state passively emits sparks that propagate easily. Akira normally doesn't use this state due to the sheer amount of collateral damage caused simply by walking around.
