Ichika and Reiner who were staring at each other for a few seconds once again charged at each other. In a direct confrontation, Ichika knew that she would not be able to win, but despite Reiner being able to match her speed Ichika knew that she was slightly faster.
Once she fully evaded the charging Reiner, Ichika knew that there would be an opening once he stopped his charge. The very second she saw that opening she used one of the Kurumi family techniques, [Zantetsuken]. Ichika's swords flowed like flowing water with a clear cut, but Reiner anticipated this move of hers and used one of the Arseid family shield arts [Iron Fotress].
Reiner moved his shield in the way of the flow of Ichika's swords and then interrupted the flow. Reiner was able to block the Ichika's [Zantetsuken] and then parried her strike causing Ichika to lose balance for the first time.
