Once the other two began fighting Surin ran up to Haruka with her two blades. Once she got close Surin raised her Zanpakuto-which had a shadow like mist rising from them-attempting to slice down Haruka's shoulder, though from Haruka's shadow another blade shot up from it attempting to pierce Haruka in her side. Surin then raised her other blade and throwing towards Haruka just in case she tried to jump out of the way, that blade had a high chance of cutting her. From that it'd show that Surin was accurate with her attacks.
