Synopsis

Theo Aspel, a weak mercenary adventurer, keeps getting kicked out of different groups. To become stronger, he summons a demon who offers a wish. But when he sees her, his wish for strength disappears.

This demon, not summoned in years, says, โ€œIโ€™ll grant your wish, but you must give me something valuable.โ€
Theo nervously asks, โ€œW-will you marry me?โ€
The demon is surprised but agrees, making them husband and wife.
They enjoy a happy married life together, causing quite a commotion wherever they go. This is a slightly naughty story about a boy and a girl.
