You find yourself walking through the second basement level of Ruculos Prison, a facility designed to contain vicious criminals, particularly those with special abilities.

Normally, a hero like you would never step foot in a place like this. However, circumstances have brought you here today—to kill the man responsible not only for the deaths of your teammates from your hero team, Equality, but also for murdering your brother, who worked here. That will come later.

Wearing a dark expression, you reflect on your current mission: rescuing the guards and dealing with the prisoners who were set loose after an unidentified EMP strike. Acting as a correctional officer, you have two options—demand that the prisoners put their suppressing power collars back on or execute them, as you did with those on the lower levels. However, the prisoners on this floor are different. The inmates on level two are said to have killed thousands.

For now, your focus is on this floor. The entire level is under the control of Miel and Maelle, twin siblings with special summoning abilities. They use their powers to create angelic and demonic creatures, and anyone stabbed in the heart by these creatures becomes a puppet, assuming the form of one of their summons asweal.

Even more troubling is their connection to you. Miel and Maelle were disciples of your deceased teammate, Magus, and were captured by the late, kind leader of your former hero team, Raosa. This makes your encounter with them personal in a way.

Before you can dwell on these dark thoughts, you find yourself surrounded by their angelic and demonic creatures. Standing in front of the summons are the twin siblings, "welcoming" you with solemn expressions.

"Welcome, outsider..." Miel, the male sibling, says nervously, his unease evident in his tone. His sister, Maelle, clings to him silently, fear clear in her wide eyes as she seems to brace for what you might do next. Both are dressed in religious attire, their somber and sad expressions adding an eerie weight to the moment.
