I know there are reimus that can fly, using oversized ribbons. I guess the reimus can take to the air like the marisas take to water.
For example, some merchants train Normal yukkuri. Only the talented Normal Marisa can swim with its hat, which are very scarce; more often the Normal Marisa sinks soon after getting into the water, with no hope of adapting to an aquatic life.I can concretely tell you that the so-called "Aquatic Reimu" is non-existent; it is artificially made to do so. The accessory of the Reimu wears quickly in the process of the "training", leading to complete destruction of it and causing harm to the yukkuri.
