Is It Wrong to Have a Different Magic Art Style in a Dungeon?

Nine years before the original story, Su Lun fell into the slums of Orario carrying the Codex of the Abyss of All Magic, and was taken in by the Familia of Justice. When the goddess inscribed his Falna, she stared at his three outrageous skills and a spell description that let him use the entire D&D spell list, then fell silent for a full ten seconds.

As the girls of the Astraea Familia complained, they watched their mage buff the whole party with all kinds of spells, while the Familia's treasury filled up with his magic items. After defeating the Black Dragon and marrying several girls, Su Lun discovered a new page slowly unfolding in the Codex of the Abyss of All Magic. What it revealed was no longer the world of the Dungeon...
