Tsukuyomi

Tsukuyomi is the released form of Rai Narukami's twin scythes, Mangetsu.

Overview
Tsukuyomi is the released form of Mangetsu, the twin scythes belonging to Rai Narukami. In this form, the weapon gains immense power, with a majority of Narukami's power being condensed into the blade. The blade has two forms, named its Phases; New Moon and Full Moon. During New Moon, the blade is pitch black, and while still exhibiting a great deal of power, is mainly meant for endurance fights as it uses less energy to maintain. However, when powered, the blade shines a bright white, and its true power is manifested, burning much more Aera as a result but becoming much more powerful for a shorter time. The edge of the white blade is so sharp that it can effortlessly cut through nearly anything, more passing through whatever it touches than actually cutting. The density of the power contained within the blade gives it incredible durability as well, being able to withstand incredibly strong attacks and being able to meet the power of stronger weapons without breaking.

Design
Tsukuyomi takes the form of a standard katana, and both forms exhibit the same general shape, with a curved blade and a crossguard in the shape of the moon, and a standard cloth wrapped handle. In its New Moon Phase, the blade is pure black throughout, and features chains that come from the pommel, wrapping around Narukami's arm. In Full Moon Phase, the chains are shattered, and the blade shines a pure white.
