Again, you are wrong , pal.

That sword, located in the cat island is an achievement itself , to unlock / pull it out , you must do the sad blue cat quests , which you can find in Chico village , there will be 6 quests and be warned that the last 3 will be High rank quest and of course , the Akantor.
