The Green Axe is an aggressive fish with a shell head which is hard and strong. Green Axe's carapace is very useful in everyday life because of its durability, but it's very expensive.
It seems to have a propensity for pursuing the soft reflected light produced by fish in the water. Therefore, you might be able to catch it with a lure that makes a big sound, which fish around here make when they hunt.
Ok, a bat-type lure that emits light and makes a rather strong sound might catch this fish.
