All I got (and I guess probably needed since I'm a stage 2 embodiment) is just a simple firing of danmaku in + and - formations at the player character, preferably colored red and blue respectively.
Basically aimed shots that are red + and blue - which I don't know if that is enough or not, I'm not exactly in the thinking mood for this.
Edit: redoing since I got a design change, and my new idea is just red danmaku that circles back, like a boomerang.
and if that is too complicated, just in straight aimed shots then, in streams. (and if it's already too late, that doesn't matter then, all your guys' choices of course)
