Asreon [The Final Warning to the World] Unique Crest Icon: Broken Star Height: ?? Age: ?? Appearance: One arm has mutated into a sharp, offensive wing consisting only of a black skeletal frame. The other normal arm has a hand, but the sleeve is an oversized 'moe' style. He wears a white military dress uniform adorned with various decorations and a commander's cap. His face is hidden, but one eye glows red. Geometric objects float around his head. A single black skeletal wing is attached to his back. He wears a cloak that partially covers his normal arm, decorated with rank insignia and various ornaments. Personality: Cold and composed. Story: He once led wars to victory and was respected by all, but he has since been forgotten, and his former glory has fallen into ruin. Attack Patterns: ⭐ 1. 「Broken Star」 — Star Fragment Zones A massive star crest appears on the ground → After a moment, the star shatters into fragments, each becoming an attack zone. Starts as one large star. *Crack*— It splits into multiple fragments. Red/black zones appear under each fragment. Fragments explode in sequence shortly after. Finally, the fragment remaining in the center causes the largest explosion. The key is that the zones are star-shaped, not just circular. --- 🪽 2. 「Fallen Honor」 When the boss ascends into the air, a massive wing-shaped zone appears on the ground. The wings then descend from above, attacking the entire area of the zone. However, the wings don't descend all at once. Left Wing → Right Wing → Both Wings. They descend in this order, forcing the player to move and dodge. --- ✦ 3. 「Stellar Trajectory」 The boss doesn't attack the player directly but creates multiple stars in the air. The stars move along fixed orbits, leaving thin linear zones behind them for a short duration. Over time, the combat space becomes filled with overlapping attack lines like this: ✦ ─── ✦ ╲ ✦ --- ⚔️ 4. 「Hero's Footsteps」 Black zones are left behind wherever the boss walks. Initially, they have no effect, but after a few seconds, attacks trigger at all previous locations. It's a pattern where following the boss seems safe, but the path you just traveled becomes the attack range. --- 🌑 5. 「Final Warning」 — The Safe Zone is the Attack This is a unique gimmick. Multiple zones appear across the entire combat area, and at first, only one spot looks safe. However, the boss warns: "Do not go there." If the player trusts those words and moves elsewhere, the spot that initially looked safe explodes. Gender: Male

First Record: [First Record]

First Record — 「First Record」 The war did not end today either. I took up my sword once again. People called me a hero, but I was a little afraid of that name. Because I thought a hero must save everyone. But today, I failed to save several people. From that day on, I began to realize. The name 'Hero' might not be a blessing, but a graveyard for those who must be remembered.
