The Night Way Before the Assault to a Certain Grand Casino (とあるグランカジノの侵入前々夜) is a special short story given to those who purchased Episode Freya in Toranoana.
Summary[]
Allen had to hold back his urge to hit Syr when he handed her the invitation to enter the Grand Casino. Despite her referring to the request as asking him for a favor, the adventurer insisted that she had threatened him, calling them the same thing.
However, as much as that task annoyed him, Allen was also worried about Syr. As her bodyguard he was quite overprotective of her, and knew she was getting into trouble. He would have preferred to tell her not to do it, but he couldn't.
In the end, he snuck into El Dorado Resort on the day of Syr and Ryuu's operation without being seen by either of them. However, thanks to the efforts of the Elf and Bell's help, his protection ended up being unnecessary.
Syr then invited him into the Hostess of Fertility to meet with Anya alone with a different smile than the one she had shown until that moment. Allen narrowed his eyes as much as he could and began to give off an intense thirst for blood. Despite that, the waitress remained unfazed, determined to get the two of them together.
Instead of clicking his tongue, the bodyguard just sighed and turned to leave. Allen twisted his mouth as he heard her sincere words of thanks mixed with a certain degree of concern for him that only he could notice.
