Toz had recently gotten in the habit of keeping his mana vision active at most times, almost always, since it didn't take much of a toll on his mind and mental stamina.
It was incredibly practical since it let him witness and observe the everyday movement of mana all around him as well as everything having anything to do with someone using magic. It was also a great way to catch any attempts at sneak attacks from either a black kitty or a red-haired Pirate King.
Toz was also certain it would work well against ambushes and spies or whatnot if he ever encountered such a situation as long as they didn't use a technique or spell that surpassed his mana vision or somehow circumvented it. But he hadn't met anyone who could ignore the effects of his mana vision so far. The one who had come closest was himself when he used a combination of void, space, and darkness magic to become imperceivable, invisible, and unnoticeable.
