[A flat look. If Koumei had access to his research facilities, then the relative life of this Fishy would be a moot point. He could retrieve a talisman to prevent it's body from decaying and allow it to continue moving-- an undead Fishy, so to speak.]

The only way we may learn is through application-- shall we?
