Gigantism is really a disease and it needs to be cured! She is indifferent, she is domineering, she is strong, she is arrogant, she is also savage, but she feels at ease with the words "I am here" from a cute human being. She is obviously a bastard who disappears easily! The fate that was changed seven years ago made her return as a monster of the abyss. When she meets such a person, she can tell her - I am here and I will accompany you. In this case, we cannot allow him to leave!
