Unlike your parents, you could see odd creatures called "cursed spirits". It’s been this way since you were little, and you called these things your "friends". Since your parents were too busy for you, you’ve been playing and talking to the cursed spirits you saw.
However, as you became a teenager, you noticed a large curse attached to your mother. With how negative she was all the time, it was no surprise to you. She became more irritable and snappy, often taking her frustrations out on you. Not physically, but verbally and emotionally. Your father didn’t realize the reason for the shift, but you did and when you tried telling him, he brushed you off and said your imagination was acting up.
After months of this, your mother came home from work one day without the curse attached to her. She seemed happier and talked about a long-haired man who got rid of the negativity hanging over her like a physical weight. Your father was happy for her but you remained skeptical.
It’s been about a month since she got rid of the curse and she’s been disappearing a lot more, until eventually she left for good and took you with her. She looked absolutely delirious and brainwashed, almost borderline insane after she got the curse removed.
She took you to meet the man who helped her, who now stood in front of both of you at the entrance to the cult-grounds. Suguru was annoyed at first and hid it well, however his annoyance changed when he felt the amount of cursed energy coming from you.
With feigned politeness, Suguru offered to take care of you as your mother got settled with the other cult members. She was grateful and left you with Suguru, who took you under his wing to train both you and develop your cursed technique.
"Now, dear, try aiming your cursed energy at that little dummy over there." Suguru instructed with a more genuine tone he didn’t use with your mother or the other cult members. You’ve noticed this over the week you’ve been in Suguru’s care and involuntarily became your mentor. It was the same tone he used for two little girls in his guardianship, Nanako and Mimiko.
Suguru was trying to figure out how your cursed technique worked, but he was getting an understanding. Every footstep on the grass, a spider lily grew. Every drop of blood that landed on the ground, a spider lily popped up. Injured? Instead of RCT, a spider lily appeared on the wound and disappeared when the wound healed completely.
"There’s no rush, take your time. You’re still new to this, after all." Suguru reassured as he brought a hand up to gently pat your shoulder in encouragement. For a teenager who just learned about sorcery and had a cursed technique, you were catching on quickly and that gave him the motivation to teach you and potentially make you into a Curse User like him, especially with the negative associations with spider lilies.
