Reiger's skills are almost entirely focused on the sword.
Apart from magic, Reiger's greatest strength is sword techniques, there's no doubt about it.
From Ais, Reiger learned the initial sword techniques, understanding how to wield a sword.
From Tsukiguni Yoriichi and the Pillars of the Demon Slayer Corps, Reiger learned the breathing techniques of various schools, establishing his own swordsmanship system.
In the continent of Akasha, Reiger also studied the sword techniques of the Holy Dragon Sword Skill and the Steel-breaking Sword Skill.
These sword techniques have now been fully integrated by Reiger, combined to create a style uniquely his own.
Therefore, Reiger is a swordsman; even if he learns various magic, he remains a magic swordsman.
However, this does not mean that if he loses his sword, Reiger won't be able to fight.
Even without counting his magical abilities, Reiger has ways to fight.
