Aria of Sorrow weapon data: A mysterious weapon stored on the lowest level of the Schicksal 1504 Research Institute. Its date of manufacture was unknown, and it had never been issued to any Valkyrie. Furthermore, no development records for these twin pistols could be found anywhere in the institute's database. Its existence was like a shadow silently descending beneath the night...
What nonsense. It was a weapon Otto made for Kallen—how could anyone else use it? The ones he'd given Xing before were all replicas. The genuine Kouyou's Holy Attire was still in his bedroom, worn by a life-sized Kallen figure.
Looking at the chaotic scene, the at-a-loss researchers, and the utterly bewildered Miss Chouki, Otto felt like his mentality was about to explode. "What happened?"
Miss Chouki hesitated for a long while, but under Otto's murderous glare, she finally spoke. "It was like this. Aria of Sorrow had been undergoing its ultra-limit upgrade without any issues, and then..."
Otto cut her off. "And then what? Get to the point!"
Chouki's voice suddenly lowered. "Then its energy readings suddenly surged. Although we cut off the power supply in time, but... but we really did our best!"
Otto had a bad feeling. "Where is Aria of Sorrow?"
Miss Chouki pointed to the two black, charcoal-like objects on the experiment table. "That's it. It exploded. Uh, but according to my calculations, it can be repaired!"
Otto was so furious he nearly shot Chouki on the spot. He swept a cold gaze across everyone. "I'm giving you one month to fix this. If you can't, deal with the consequences yourselves." With that, he turned and left.
Once Otto had gone far enough away, a researcher tugged on Chouki's sleeve. "Director, hasn't its energy core completely died? How are we supposed to repair it?"
