### Epilogue: Null's Echo (Rounds 451-500)
The Sanctuary sealed, Aetherion holding **Null's Essence**, its light pulsing. Null's voice whispered, "Zion… I return," Rin's music resonating, his envy deepening as he stood beside Aetherion's might. Gringo vowed revenge, his shadow merging with the Anti-Void.
The glove's seltzer misfire silenced, the multiverse trembling. Null's revival loomed, Rin's envy a fragile thread, the team's unity tested against the future.
Then unexpectedly, the Lie in the April theme song starts to run. Everyone starts to find the source. Void says "... love song?" They see that *All* is wearing headphones listening to songs but his phone isn't plugged in with the headphones. *All* stops abruptly "uh ... .Plot Development?" He says and turns off the song. Aetherion is suspicious and says "are you a late night Otaku with cold coffee? This seems just like it", All replies by saying "no no. It's just connected to Narrative Concave Amphitheater." Wait what,says Aetherion. *All* shutters "you don't need to know what narrative Concave is." then Rin says "mate, really listen to romantic songs, eh?" *All* gets annoyed "hey! I am the OTP of this Novel. At least now, until the Author-self-insert takes over"
