mikazuki munechika
A Touken Ranbu character. Based off of the tachi Mikazuki crafted by Sanjou Munechika currently housed in the Tokyo National Museum as a national treasure. One of the "Five Swords Under Heaven", along with Juzumaru Tsunetsugu and Oodenta Mitsuyo.
In-game, he appears as a blue-haired young man with blue eyes. He wears a black hairband with golden tassels, black gloves and a hakama skirt underneath a sayagata patterned kariginu. The crescent moon imagery invoked in his name (三日月 = Crescent Moon) is seen in his casual wear bandana and on the sides of his standard clothing.
Tends to be characterized as an "old man" in fanworks, since he introduces himself as an old man due to being "born" near the end of the 11th century. This either manifests in a wise, ancient personality or that of a doddering old fool in comedic works. For the most part he also tends to be characterized as a rather teasing person based on a few of his lines. Knows a thing or two about Honebami Toushirou's past, but refuses to tell him anything about it.
He shares the same name as Mikazuki from Kantai Collection due to the historical ship being named after the sword, and as a result is often paired with her in various crossover fanart. Their grouping is tagged 三日月爺孫 ("Mikazuki Grandfather-Daughter") in pixiv, as Mikazuki the sword spirit is a self-proclaimed old man (and thus the grandfather), while his ship-girl counterpart is a very young girl (hence the grand-daughter).
Because of his status as one of the hardest to obtain swords in the game, he's become rather infamous, and has appeared in multiple media as a borderline mascot for the franchise.

在游戏中，他表现为一名蓝发蓝眼的年轻人。他戴着带有金色流苏的黑色发带，戴着黑色手套，身穿袴裙，下身穿带有 Sayagata 图案的 kariginu。他的名字（三日=新月）中的新月图案出现在他的休闲装头巾和标准服装的两侧。
在同人作品中往往被描述为“老人”，因为他因“出生”于 11 世纪末而自我介绍为老人。这要么体现在一个睿智的、古老的性格中，要么体现在喜剧作品中的一个老糊涂的人身上。在大多数情况下，根据他的几句台词，他也往往被认为是一个相当好笑的人。对根波冬四郎的过去略知一二，但拒绝告诉他任何事情。
由于这艘历史船以剑命名，他与舰队收藏中的三日月同名，因此经常与她在各种跨界同人作品中配对。他们的组合在pixiv上被标记为三日月爷爷孙（“三日月爷爷-女儿”），因为剑灵三日月是一个自称老人（因此是爷爷），而他的船女对手是一个非常年轻的女孩（因此是孙女）。
由于他是游戏中最难获得的剑之一，他变得相当臭名昭著，并作为该系列的边缘吉祥物出现在多种媒体中。
