*Chapter 2: "Reckoning Prep"*
Yun gripped the worn backpack straps, eyes locked on FF Academy's steel gates 🏫. Ten years old, and the city's most elite demon slayer school awaited. Rumors said it was harder to get into than Heaven's front door 😏.
Mom's voice echoed: _"Use _The Grim series_. Trust no one."_ 🔮
Yun adjusted the hidden sword—illegal for students, but _rules are for others_ 😎.
Elara appeared beside him, smirk intact. "Guess you're not _just_ a Rider myth."
Yun raised an eyebrow. "What're _you_ doing here?"
"Audit." Elara winked. "Plus… FF Academy's got _angels_." 😈
Gates swung open. Cadets streamed in—future demon slayers, Heaven's pawns 🦸♂️.
Yun's earpiece crackled— _"Yun Rider. Report to Dean Ryker."_ Guild priority 🔔.
Elara nudged him. "Looks like you're on the clock."
Yun nodded. _Time to play._ 😄
Dean Ryker awaited in his office—skull-faced, piercing gaze 📸.
"Yun Rider. FF Academy's… irregular rules apply." Voice like gravel. "Demon slayer lineage, _The Grim series_, Lucifer—"
Yun's eyes snapped up. "What about him?"
Ryker's smile was thin. "You're here to master _Grim_ power. Don't get used."
Elara leaned in (had she slipped in?). "Sounds like _welcome to the danger zone_ 😈."
Ryker ignored her. "Cadets. Survive _Hell Week_. Prove you're _Grim_ worthy."
Hell Week: survival trial by combat, magic, mayhem 🔥. _Hell Week has a hidden agenda_: FF Academy's testing _The Grim series_' true power 🔮—push cadets to unlock it.
Yun grinned. _Bring it._ 😎
*Grim page 3:* _"Tenebrae ignis—"_ (darkness ignites)
Office flickered— _shadows curled_ 🔮.
Ryker's eyes gleamed. "Interesting."
Elara whispered, "You're _not_ normal, Rider."
Yun shrugged. _Time to find out._ 😄
Cadets dispersed—rushing to prep. Yun's phone buzzed: _"Elara: Meet. Dumbwaiter. 23:00. _Grim_ talk."_ 💬
Yun smirked. _She's in._ 🔮
23:00—dumbwaiter creaked, shadows inside 🔮.
Elara whispered, "_Grim_ pages react to you… like _heavenly_ code 🔮. What's your angle?"
Yun leaned in. "No angles. _Grim_'s my tool."
Elara's smile hid secrets. "We'll see 😈."
_Grim page fluttered—_ *"Mortis… expect."* 🔮
Yun's eyes narrowed. _Expect the in expected
Hell Week starts tomorrow 💀. _Angels infiltrated FF Academy_: Elara's info was on point—heavenly spies tracking _Grim_ users 🦸♂️. Yun's reincarnation memories flicker: glimpses of _past lives_ as a Lucifer foe 💀.
