Tokiko uses Sekkai in the same scene in the manga, too. The real problem is Spatial Phasing. I'm pretty sure there's a scene where Tokiko discusses it with Tokine in depth, but I can't remember where that is in the manga. But the fact that Tokine uses it against Reiji Kakushino makes me think it occurs before then, unless it's a flashback.
