A Manga With Too Many Premises is a one-shot Yuri Genre manga by Tamamusi. It's a love story between two women, Yuna and Ryou, that crams as many of the genre's story premises and cliches into a manga as possible.
The manga contains examples of:
- Age-Gap Romance: Ryou is a high school student, while Yuna is an Office Lady, meaning that they are probably at least five years apart.
- Brother–Sister Incest: Yuna and Ryou are half-sisters with the same father and end up falling in love in spite of that.
- Childhood Friend Romance: Yuna and Ryou knew each other when they were younger.
- Contrived Coincidence: Yuna and Ryou not only run into each other by chance in the middle of a large city, but moments after they encounter each other, their father finds them together and reveals that they just so happen to be half-siblings.
- Exactly What It Says on the Tin: The manga is all about combining as many story premises for Yuri Genre manga as possible.
- Extremely Short Timespan: The manga covers a single encounter that lasts no more than five minutes.
- "Freaky Friday" Flip: Yuna and Ryou switch bodies as a result of kissing.
- Mind Screw: When so many premises get to be cramped together, this is bound to happen.
- No Ending: The manga ends after Yuna and Ryou switch bodies.
- Random Events Plot: Two women meet each other and their father by chance, after which things spontaneously happen.
- Speak in Unison: After Ryou and Yuna recognize each other at the same time, they say, "Didn't we use to play a lot together when we were kids?!" at the same time.
- Telepathy: Both Yuna and Ryou can read people's minds by touching them.
