Here's our main couple, cosplaying as high schoolers; because they love to costume, and love to coordinate, and it's just ghastly to wear the same things too many times.
Iannis plays up the feminine charm while Paimon wears his coat like a banchou, sweet as always but always getting into trouble.
Auu...he likes Iannu-chan, the Student Body President, but how can such a reputational person be seen with a delinquent like himself? More importantly, can Iannis resist his bad boy charms and devil-may-care attitude?
Such are the stories the two love to weave. To capture the innocent, carefree times they never had in reality. To explore the many facets of each other as lovers, no matter the world or the time.
No matter which universe they are born into, they will find only each other on the road of life. No puzzle worth solving save the heart of the other.
