Description
Shouko Kirishima is the class representative of Class A at Fumizuki Academy and the top academic student in her year. She has long, dark purple hair often styled in a hime cut, purple eyes, and stands 160 cm tall, typically seen in the standard school uniform.

She is a childhood friend of Yuuji Sakamoto, having met him in the fifth grade. He treated her normally despite her wealthy background, which led her to develop strong feelings for him. She promised his mother she would marry him when they grew older. This dedication solidified after an incident where Yuuji protected her from older students vandalizing his desk and told her to leave for her safety, followed by a conversation with his mother.

Shouko is generally calm, composed, and soft-spoken, but exhibits extreme possessiveness and jealousy toward Yuuji. This results in violent reactions if she perceives infidelity, such as using a taser, poking his eyes, or chasing him with weapons like a nail bat. Despite this, she trusts him completely and believes everything he says, even when deceived. She is a long-term planner who has already chosen names for their future children and is notably inept with electronic gadgets, often breaking them, though she can use a taser effectively.

Academically, she is exceptionally intelligent with a perfect memory. Her summoned being appears in samurai armor wielding a chokutō sword, though a system error once caused it to manifest as an adult version of herself wearing lingerie and an apron.

Her primary motivation across storylines is her relationship with Yuuji. She possesses a rejected marriage contract due to their age. In one arc, she deliberately lost a summoning tournament after being tricked into believing Yuuji would propose. In another, she was deceived into playing a dangerous water game. Some narrative elements suggest potential development where outside perspectives prompt reflection on her behavior, though this remains unrealized.

She is considered a divisive character due to her abusive actions being played for comedy and a perceived lack of sympathy from some viewers who find her actions unjustified.
