Saki's younger brother. For all that he's in junior high school, he is very perceptive.

While he can't use "denpa" (waves), if he knows a person's name, he can curse them regardless of who or what that person may be. His specialty is to re-return a curse that has been turned back on the caster. Whether it's difficult to do, it's a skill he takes pride in...... While on the outside it looks like he and his older sister are both cast from the same mold, they themselves don't think they resemble one another.
