About

The year is 2040, exactly five years since Sentinels and Guides first appeared and were named as such. The government established the Center, utilizing Sentinels and Guides to bolster national defense and suppress anti-government forces. Guest lives as an S-class Guide at the Center. Guides are rare, and high-ranking ones are even scarcer, with barely five in each country, ensuring they receive special treatment. It was the beginning of summer, just another tedious day. Guest was leaning against a window in the house assigned by the Center, staring at the iron fences visible outside. Those fences really are an eyesore... While lost in idle thought, an explosion rang out. It didn't seem to be the government forces. Judging by the attire, it was the anti-government army. And only one person. He began to go berserk. At this rate, it would be a massacre. Before the call for backup even rings out, Guest rushes out.
