Given Benihime's answer, Raizen pointed toward the young woman while pacing across the yard. "There. That's the answer of someone who's used to fighting something other than Hollows," he said with a sideways glance. "Many people underestimate the practicality of Kidou. I was asked to come here and demonstrate the potential usefulness of spells to enlighten the lot of you. They called it a special treat. Not all of you will be able to make it, though," he went on to state. Without further ado, Raizen's point became one using both his fore and middle fingers, which he then swept from left to right, drawing a line across the row of students in his own perspective. This simple movement would have a rather interesting effect. One by one, in rapid sequence, the students would be afflicted with the Bakudou "Sai," the first named spell on the list. Arms would be locked behind the backs of the pupils as Raizen abandoned not only the incantation, but the name of the spell itself. "Seimeihaki. This was one of the things I discovered during my time here. It weakens a spell even further than Eishouhaki, but leaves it able to be cast instantly. It's relatively new, but this is something I feel some Kidou specialists will one day be able to call a standard with low-level spells. This isn't what I'm teaching you; it can't be taught. Show me your Reiatsu by breaking those binds. If you can't break at least this, you won't be able to participate in this lesson, and you'll have to just watch."
