Revision 1

The Karasuma clan is one of two samurai houses confirmed for SOL Shogunate and the antagonist family of the campaign's opening arc. Its power flows from lunar mining and material processing. It instigated the massacre of the rival Tennoji clan, and it hunts the surviving Tennoji heir through every channel the regime gives it. For the wider political frame, see The SOL Shogunate.

Quick Reference

Mining and Material Processing

Where the Tennoji owned the lines between places, the Karasuma own what comes out of the ground. The clan's power flows from lunar mining and material-processing operations, and both of the holdings named so far are extraction sites rather than administrative seats. On a Moon where the elite live inside engineered domes, the industry that supplies the raw material for all of it is a heavy lever.

The clan also sits inside the scientific edge that defines the Shogunate's ruling caste. Genetic engineering, biological adaptation, and habitat and life-support research flow first to the houses that can pay for them and reach the working population on far worse terms. A mining workforce sits on the wrong side of that split by definition, though the studio has not described conditions in the clan's operations directly.

The Strike Against the Tennoji

The Karasuma moved against the Tennoji in a coordinated strike and wiped the clan out. The framing is consolidation rather than grievance: removing a rival and improving the Karasuma position inside the Shogunate. It is the event the campaign opens on, and it is the reason the player character has no house to return to.

The individual responsible has not been named. Neither have any bosses tied to that figure, so the chain of command inside the clan is entirely undisclosed.

The Hunt for Yuzuki

Yuzuki survived the massacre, and the Karasuma pursue her through every Shogunate channel available to them. Because her clan is gone and her standing with it, that pursuit is legally uncomplicated: she is an outlaw, and the regime that should have protected her is the instrument being turned against her. Her revenge plot against the clan is the doorway into the wider conspiracy the campaign is actually about.

Named Holdings in Official Art

The studio's concept art carries location labels that go further than any published marketing copy. They are the studio's internal names for the places pictured rather than descriptions of confirmed playable content, so read them as a guide to what exists rather than as a finished gazetteer.

The studio has published a short piece of lore about the Daibutsu itself. It describes the colossal Buddha of the mining town as reaching back to the very beginnings of human residence on the Moon, hewn from the rock of the Moon itself, and frames it as a testament to the urge to find beauty in the most desolate and isolated of places. That places the landmark well before the present-day rule of the Shogunate. How the Karasuma came to hold it has not been explained. For the wider region, see The Moon.

The Mended Sakura Tree

One of the short in-fiction entries the studio has published, attributed to a record called the Shogunate Archives, describes a domed park from an earlier colonisation in which a treasured sakura tree grew to enormous size in the Moon's low gravity. Brutal wars broke the dome. The tree froze, cracked and died, and the entry ties its death to the death of any hope of lasting peace.

In the present era the Karasuma have reclaimed that tree and repaired its cracks with gold kintsugi. The entry states plainly that the repair is meant to symbolise the clan's dominance over lunar resource extraction and over the lunar landscape itself. These are the regime's own records rather than a neutral account, which is part of the point: the clan is writing down what it wants the mend to mean.

The same craft describes Yuzuki's gold-veined body, so the motif runs in both directions in this setting. On Yuzuki it reads as a survivor rebuilt from her own breakage. In Karasuma hands it reads as a victor's monument to breaking something else.

The Name Gensai

One concept-art label describes Karasuma Crater as the "seat of Gensai". That label is the only place the name appears. The studio has not otherwise introduced it, so nothing about who or what Gensai is should be assumed: the word could name a person, a title, a house, or a place, and this wiki takes no position on which. It is not treated here as a character, a leader, or a ruler, and no future edit should promote it to one without a published source.

Unconfirmed Details

The clan is defined so far by its industry and its actions rather than by its people. Not published:

• The clan leadership, including the figure who ordered the massacre.

• The clan crest, colors, formal titles, and internal ranks.

• What Gensai refers to.

• Whether either named holding is a playable location.

• The scale of the mining operation and the conditions of its workforce.

• Whether the Karasuma answer to the Shogun directly or operate with more independence.

• Named bosses drawn from the clan, and where they sit in the campaign.

• Whether the clan held its position before the earlier colonisation era the archives describe, or rose afterwards.
