Sanae Tsukimoto, our deadpan girl from Karakai Jōzu no Takagi-san
Use sanae_tsukimoto to summon her, use black hair, short hair, black eyes, forehead to form her head, use school uniform, sailor collar, serafuku to summon her default school uniform
You may need a jitome tag to make her eye half closed like in anime where she always makes expressionless face.
