I Thought I Was Dreaming

[Dropped. Posting the outline]

Saneda Haruka is an utterly ordinary high school girl.

She isn't like her childhood friend, the boy she grew up with, a high school detective who could appear on TV; nor is she like her childhood friend, a national-level karate champion; and she is nothing like her close friend, the heiress of one of Japan's leading conglomerates...

The one slightly unusual thing about her is that she dreams.

In her dreams, she doesn't transform into a magical girl, but she does get a mysterious card-drawing System.

Though the things she draws are all strange and unusual...

N Card [Blind Person's Sunglasses] A magical pair of sunglasses that makes the wearer blind

N Card [Water-Entry Bandages] Sturdy and breathable, apparently designed specifically for entering the water, and quick to dry

R Card [Technical College Student Uniform] An uninspired, tacky dark-blue outfit. If you like, you can customize it a little

UR Card [Itadori Yuji] A good big brother who worries about his little sister and follows her around to protect her

Saneda Haruka: ??!

Wait, hold on!!

Did something weird just get mixed in here?!

Notes:

1. When they're little, the relationships are all platonic and familial.

2. There is a male lead, but the romance is almost nonexistent. [The male lead's appearance is practically the ending]
