After the Seitei forms, the first set you meet in Musō Shinden-ryū proper is Shoden — the Ōmori-ryū. It is where the school's own character starts to show.
What "Shoden" means
Shoden translates roughly as "first transmission." The set is built on the kata of Ōmori-ryū iaijutsu, with one variation that belongs to Musō Shinden-ryū alone. All of these forms begin from seiza, the formal kneeling posture. That single fact shapes everything: you are drawing, cutting and sheathing from your knees, which makes demands on your hips and balance that a standing draw never does.
These became the first set in the curriculum when Ōe Masamichi reorganised the older Hasegawa Eishin-ryū material at the start of the twentieth century. So although they are taught first, they are not "basic" in the sense of being simple. They are foundational, which is a different thing.

A few forms worth knowing about
Two of these have stories attached that make them stick in the memory. Ryūtō, the sixth, uses a deflecting technique (ukenagashi) and is often called the hardest of the set — the timing of receiving and turning the attack is unforgiving. Juntō, the seventh, was not made for a duel or for self-defence at all; it represents the act of a second at a ritual suicide, which is a sobering thing to learn and a reminder that these forms carry their century with them.
The twelfth form, In'yō Shintai Kaewaza, was added by Nakayama Hakudō himself as a variation on the fifth. So even this "old" set has a modern fingerprint on it.
Why beginners struggle here, and why that's fine
Coming off the Seitei forms, students expect Shoden to feel familiar. The shapes do carry over, but doing everything from seiza exposes weaknesses the standing forms let you hide. Your knees complain. Your draw, which felt clean standing up, suddenly snags. This is the set teaching you to root your movement in your hips rather than your arms, and it takes time.
The kneeling forms are not a stepping stone you leave behind. Senior practitioners return to them precisely because there is nowhere to hide.
What comes next
After Shoden comes Chūden, the Hasegawa Eishin-ryū set, performed from tatehiza with one knee raised, where the lesson shifts toward creating cutting distance by stepping back. Beyond that lies Okuden, the inner transmission, with both seated and standing forms. We sketched the whole map in Where Musō Shinden-ryū Comes From.
