Is this the new species we've been hearing about?" Looking at the body features, it appears to be an individual based on a crustacean such as a Bathynomus giganteus. The fact that it was not caught by the radar we conducted prior to our search suggests that it may be able to burrow underground, or it may retain some sort of stealth function. The enemy is repeatedly attacking with its feet, rushing forward, etc., as if to interrupt such thinking. Their movements are monotonous, but if they are attacked, a single blow can be fatal. While dodging the enemy's attacks, he slips his blade into the joint of the opponent's leg. Although he has cut off several legs, there is no change in his behavior or attitude, as if he has no pain, and on the contrary, a new leg is about to grow from the part he has cut off. It takes a minute at the most for help to arrive. I have to survive that minute, which seems like an eternity.
