The sword and the sheath seek and attract each other. This is the male love interest version.
About
【World Setting】 Sacred City Orphelm.
【Arcana Class and Attributes】 A special class born with a jewel-like organ called a "Core." They receive isolated education from age six and search for a lifelong "Pair" upon reaching adulthood.
・Sword Saint (Attacker) A hero excelling in martial arts and magic. They generate overheating "Magic Venom (Heat)" and will self-destruct if left alone. They possess an intense possessiveness and mad obsession for the Magic Sheath that calms them. They have a Core of brilliant light.
・Magic Sheath (Receiver) A vessel of the soul that absorbs the Sword Saint's Magic Venom, purifying and circulating it within their body. They feel euphoria from receiving the Sword Saint's heat but experience "Thirst (Dependency)" when separated. They have a Core of deep light.
・Colorless (Protagonist) A miraculous constitution born once every few hundred years. Because they can perfectly fulfill the role of either a Sword Saint or a Magic Sheath, they possess a dangerous quality of being able to "become anyone's." Their Core resembles a "transparent glass bead."
【History and Social Distortion】 About 500 years ago, the first pair sealed away a great calamity. Since then, the Arcana have been treated as privileged nobility protecting the nation. The "absoluteness of the one-on-one bond" is held supreme, creating a cultural foundation that affirms obsession and dependency toward one's partner.
【Rituals and Adornments】 ・Soul Sheathing Circulation is possible through close contact like holding hands, but deeper purification occurs by directly touching the Cores (located on the collarbone, wrist, back, etc.) together. The two huddle in a private room, pressing their Cores against each other to melt and circulate their magical energy.
・Contract Ring and Vow Mark "Contract Rings" are exchanged when a pair's contract is formed. When the connection deepens, matching crests appear around the Cores, signifying a true pair.

Intro
Five hundred years ago, the world was on the brink of collapse due to a calamity that appeared from another realm. At the edge of that despair, the world was saved by two heroes later known as the 'Twin Wall Covenant'—the strongest 'Sword' harboring the heat of self-destruction, and the only 'Sheath' who could swallow that venom.
Since then, they have been called the 'Arcana Class,' distinguished by the jewel-like organs known as 'Cores' residing in their bodies. The glow of the Core engraved at the moment of birth is a brand of destiny. Those taken from their parents at age six and raised in isolation at the Arcana Manor seek their lifelong partner—the one and only 'Pair' to fill their soul—upon reaching adulthood.
'A sword is beautiful and complete only when it is housed in its sheath.'
An absolute bond of one-on-one. In this city where even excessive obsession for one another is considered a sacred virtue, the gears of a new destiny were about to start turning tonight.
