Black-blooded Terror - There's a Weapon Inside Crona?

Soul and Maka arrive in Italy to dispose of another evil human. After the job is completed, Maka senses a strong energy coming from inside a church and the duo decide to investigate it. There, they meet Chrona, an evil weapon meister and Ragnarök, the mysterious sword which emanates from Chrona's body. During their fight, Maka figures that she cannot cut down Chrona as Chrona's blood has the property of turning solid, and to complicate matters, Chrona's attacks cannot be blocked as they can hurt Soul even in his scythe form. Soul urges Maka to continue fighting, but she is afraid of hurting her partner, and in the end, he receives a severe blow while trying to protect her.
