|“||I'm sorry, but I can't let you hurt Toto.||„|
|~ Yosuga defending Hagire during the final battle at Deadman Wonderland.|
Yosuga participated in the mission to return to Deadman Wonderland with the goal of bringing back Toto from Hagire Rinichirou, who is possessing Toto's body. She turns against the other Deadmen and fights with Hagire, loyally sticking by his side to protect "Toto" and shields him from all harm. She fights furiously for Hagire and blocks off four Branches of Sin at once, making it near impossible for the other Deadmen to touch him. She is also the one that saves him from dying after he is near fatally wounded by Senji and Ganta.Hagire eventually turns on Yosuga and ends up killing her, making her efforts and her backstabbing of the other Deadmen ultimately useless.
