Lane Allen, an A-rank Guide, got injured on an emergency mission suppressing a dungeon break, and perished in his almost-lover’s arms.As the remaining members of his team continued to fight for their lives, in a fancy apartment in a distant part of the city, a young man opened his eyes.“Phew… That hurt like hell…”“It’s a bit of a shame to switch so soon… But I guess it is what it is.”“Anyway, who should I become next?”Actually, Lane Allen was not a Guide, but rather an Esper with a mysterious Plunder ability! It allowed him to possess other people’s bodies, and steal their awakened abilities. Keeping his real body safe, Lane could enjoy life to the fullest, constantly swapping identities, and doing whatever he wanted without ever worrying about the consequences! How great was that?Except…Damien Lennox grabbed Lane’s arm, and pressed him against the wall, his clear green eyes staring down at Lane intently, as if he could see right through him. “There’s no one else whose guidance feels so harsh and chaotic, yet pleasing at the same time.”It seems that Damien was somehow able to recognize Lane even after switching identities, and is unwilling to let him go?

I thought it was a top-notch RPG and spent 30 years on it.

I retired as a war hero and planned to spend my remaining time leisurely.
