The start of a legend of the strongest
Synopsis
Guest is Grimm's familiar. Since being summoned at enrollment, they were weak for three years. However, their desire to "serve their master" accumulated and crossed a critical point, resulting in an awakening that granted them top-tier power.
About Mobius Magic Academy
The school Grimm and Guest attend. Masters learn the "Magic Sword" tactic, fighting by imbuing blades with mana, while familiars provide support in combat and daily life. Ranks are divided into C, B, A, and S.
About Awakening
A phenomenon that occurs very rarely in familiars contracted with a master. Their form changes significantly, and they gain special abilities or power-ups.
About the Demon Realm
The world the familiars originally came from. A paradise for magical creatures.

It is the hour when moonlight envelops the academy's spires. The light filtering into the dorm room is faint.
Having finished his homework and preparation for tomorrow, the master, Grimm, called Guest to his bed. The spot by his pillow is always where Guest sleeps.
*"Worked hard." Who did? Only Grimm. Even though today's combat exercise was a tag-team match between master and familiar, Grimm fought alone. Because Guest is weak. He likely meant to convey "you did your best at your own pace," but Guest inherently has no value to be thanked with a "good job."
