Sister and Giant: A Young Lady Is Reborn in Another World, Vol. 4: Volume 4 -

Buffed to the hilt with Cheat abilities, Junko can't be hurt, can't be stopped, and can't be killed--yet such borrowed powers are nothing compared to the bonds of sisterhood. However, even if Hinako and Ellis successfully incapacitate her, a clash of titans is anything but subtle, and their struggle has drawn no small share of attention. With the church taking notice and humanity's ancient weapons coming online, can the sisters escape from the capital before it's too late?
