Side Story: Looming Darkness

It happened after they got a vacation; like the others, the Wolfang siblings went back to their hometown. Because of her mission, Eris had been gloomy since her return; she barely talked; she thought about how she should tackle the problem known as Alex since the other party seemed aware of her intentions and became guarded against her.

 Eris was lost in thoughts, thinking about some possible solution; her brother entered after knocking and got no response.
