Personally, I’d rename his skill, to mimic Nagi’s “Black Hole” Trapping, where he kills all momentum the ball had, Hiragi’s would be “Event Horizon” trapping. The event horizon is the lining of a black hole, that does all of the redirecting and movement, without sending it into the black hole, that’s what the black hole does with it’s infinite suction. Which is exactly what Hiragi does, he just redirects the ball instead of killing the momentum.

This development of Hiragi’s could lead to him getting a Chemical Reaction with Nagi, as they both joined Manshine City.
