Why the fuck is Yuno always the one who gets buffs ? I mean he already has everything, two grimoires, spirit magic, an insane amount of mana, and many more, and now he can even use anti-magic ???
did you actually read the manhwa ? If you really pay attention to it, then you will know that he did appear when Jinwoo fought the monarch trio (frost, beast, and insect), and when he fought the Dragon King.
