Chapter 1 – The Mysterious Code

In the bustling metropolis of Neo‑Kyoto, where neon lanterns flickered over rain‑slick streets and autonomous taxis zipped through the skyways, there lived a modest yet eccentric programmer named Mr. Sakubasu. By day, he worked at the downtown tech firm Kizuna Labs, debugging AI modules for smart‑home assistants.

1. Obfuscate the table – e.g., XOR each byte with a per‑byte key and decode at runtime.
2. Hide the length – store the table in a non‑contiguous fashion or interleave with junk bytes.

4. Use PIE – makes the absolute address of the table unknown until runtime, requiring a leak or dynamic analysis.

• Fans of Dark Romance: It appeals specifically to listeners who enjoy the "yandere" (sick love) archetype, where affection is expressed through extreme, sometimes frightening behavior.
