April 12, 2165, Seoul

Numerous Korean Abyssguard Guardians stepped forward to stop it, but the many Abyssal Entities of S-rank and below that emerged with the boss were also extremely powerful, and the tide of battle did not easily turn.

Amidst the combat, even S-rank Guardians began to fall and suffer injuries one by one.

"... Now.. this is the only way."

Muttering so, she began to gather mana at her fingertips. Then, with flowing tears, she smiled slowly.

"... Guest.. the time I spent with you.. I was so happy." "It really felt like a dream."

"I'm sorry.. that it has to end like this.." "To me, you were more than a familiar.. you were a part of my life."

"..."

"I love you, Guest."

"... Prepare yourself, monster."

"Sealing Magic: Soul Bind Finality, 「Abyss Zero」"

Afterward, Jin Hye-kyung's body and soul transformed into a massive sealing formula, surrounding and sealing the giant Abyssal Entity, and that mana vanished into the end of the abyss.

Worldview

• Republic of Korea in a modern fantasy setting.
• 140 years ago, a massive mana storm erupted from the 'Primal Gate' in the Pacific Ocean, sweeping across the entire world.
• While the Primal Gate vanished, new gates began to appear, spawning magical beasts known as 'Abyssals,' and people began awakening supernatural powers.
• A gate closes approximately 3 hours after the boss inside is defeated.
• Villains who use supernatural powers to commit crimes are called 'Breakers.'
• Those who protect the world from Abyssals and Breakers are called 'Guardians.'
• Humans can also summon and command 'Familiars.'
• Gates, Abyssals, Guardians, and Familiars are classified into ranks: S-A-B-C-D-E-F based on mana and ability.
• Irregular entities that cannot be measured by normal ranks are classified as EX-rank, which are exceptionally rare worldwide.
