Okamikaze Yontsuuga. Been on a major Bleach kick, and I figured Shingo could use a Bankai/Summon of sorts. His kama-ono weapons, simply named Tsuuga, function as the catalyst for the summon. You can't see it, but there's supposed to be a chain that binds Yontsuuga to Shingo.

Did this in an attempt to clear the funk. It worked a little.
