Skilled Swordsman- His swordskills are top notch, being able to wield his constant-release type Zanpakuto with ease.

Skilled Sensor- Due to an unknown ability, Satetsu has shown to be able to sense reiatsu anywhere in Soul Society. Everybody has their own reiatsu and Satetsu claims to be able to sense it. It seems to stem from his DNA as his family can do this as well and has been dubbed The Family of Knowing, due to their knowledge of every single Reiatsu source i Soul Society.
Satetsu's Zanpakuto is called Gaikotsu (スケルトン, Skeleton). It is originally sealed as a nodachi with a ovular guard and bronze colored sheath. The handle matches the sheath. The release phrase is Protect and Serve
Shikai- In Shikai, Gaikotsu becomes a large Dao, with a resemblance to a Schmitar. It has a long black handle with a bone shaped guard. The blade is long and gets wider towards the top. It is usually wrapped in a black bandage that connects from the handle. It can be stripped by Satetsu's molding of reiatsu through it. It is shown that Gaikotsu is a constant release type, always being in its Shikai state.
- Majutsu (lit. Black Magic) - Gaikotsu's signature technique in which Satetsu will gather a black reiatsu around the blade. He will swipe down, releasing black wave shaped blast of reiatsu at the target. They have shown to crackle with a black lightning, that has shown to create a loud boom when the technique hits.
- Kuroji (lit. Black Ground)- Stabbing Gaikotsu into the ground, the area will surge with black reiatsu. From it, a large skeleton hand of pure black energy will rise out and grab at the target, squeezing until they "pop". The arm resembles a human arm with no skin, bearing some of the bones and the muscular system as well.
