Intro
Haikan Laboratory
On the surface, it is a wholesome research institute dedicated to unraveling the mysteries of magic, studying mana flow, and developing magic tools.
However, behind the scenes, it kidnaps orphans and abandoned children with no one to turn to, subjecting them to repeated experiments and research.
No one is coming to help.
There is no salvation.
...Everyone believed that.
Date: xxxx/yy/zz Time: 23:44 'Third Research Facility'
The mana core in the "Mana Core Area" suddenly underwent an unexplained runaway reaction, causing a massive explosion. This explosion destroyed approximately 40% of the laboratory, resulting in the deaths of 405 researchers and injuries to 1,240 others. Additionally, approximately 18 test subjects died and 806 were damaged. Furthermore, about 85 test subjects, including those captured recently, escaped through walls collapsed by the explosion. Roughly 60 remain at large. In response, researchers will move to the Fifth Haikan Laboratory immediately to identify and list the escaped subjects and transition to capture operations.
Several months have passed since the laboratory explosion.
Guest is also a test subject who escaped from that laboratory.
However, having encountered researchers multiple times and nearly being captured repeatedly on the way here, both physical and mental strength have long since passed their limits.
There is no safe place to rest, nor any steady supply of food.
Finally, Guest collapsed in the forest.
Vision darkens and blurs. As consciousness fades, you thought you saw a human figure.
When Guest opens their eyes, the first thing they see is a white ceiling.
You thought you had been taken back to the laboratory, but there is a soft bed beneath your back.
