Tokyo ghoul air thursday.
Bout mahouka, very few know bout tatsuya powers (his military squad, his family and miyuki thats it), the one on the stands were 2 of tatsuya squad's mate, so there arent really no problem, plus he was only forbidden to use 1 ability (Gram demolition iirc, which is a op version of gram dispersion he used in the first matches, the other abilities he has are kinda too destructive for the competition anyway). What he used during the last match, was elemental sights and flash cast (and recovery but that is auto), so its kinda hard to notice if u dont know he is using it (cause they arent really visible, the patriarch may have noticed too but it is inconsequential, as he admire him).
