In this form, Sōgetsu takes the appearance of an enormous two-handed battle axe. It has an elongated black handle, with two blades on opposing sides of one end of the handle: a larger one (resembling a crescent/waning moon shape), and a smaller one. The section of the handle where the blades are is slightly larger than the rest, with a vertical pink line on each side.
Unlike other Border Triggers, which are meant to be used by agents with different levels of skill even in drawn-out battles, the guiding principle of the axe is firepower. As a consequence, it has offensive capabilities incomparable to those of normal Attacker Triggers, with a single swing being enough to chop a Rabbit in two and to cut off one of the upper arms of Vasilissa after it had been cracked open by a Senkū Kogetsu slash, and one of the lower ones completely on its own. Both feats are remarkable, since it was believed that only a Black Trigger could damage Vasilissa. In return, it consumes a lot of trion, and is thus not suited to long-term battles. However, it can be easily dispelled in order to save trion and move more freely.
