Bruuh he's got the Sword of Actuation from Berserk x 100
Also, I wonder if Akutagawa was telling the truth about his "lung disease" or if it was just a lie he told to set the plan into motion...?
Also, It's been a few chapters since Ranpo did something, I'll be he's planning to Yoink the sword and bring it into the book with him, somehow.
