4 parts Complete Yu Gi Oh! X Pokemon X slight! Super Danganronpa Another 2 crossover
Setsuka Chiebukuro was reincarnated into a new world after her murder. She awakens in an orphanage as the supposed sister of Seto and Mokuba Kaiba.
Forgotten and left behind by her older brother, Setsuka ran away from the orphanage and into the unsuspecting arms of the famous Galarian Dojo Master Mustard who was on holiday at the time. She was then adopted by the elderly man and by doing so, getting as far away from the orphanage even from her brother as he became rich and famous in the Duel Monsters region.
Arriving to the lands where Pokemon roam, Setsuka changed her surname to her previous one from her last life to give herself a sense of self and identity without the help of her brother's surname.
Now, years later, Setsuka returns to her homeland, if only by accident. Or was it? Arriving at Pegasus's island she meets Yugi Moto and his gang. Call it a hunch, but Setsuka senses something off about Yugi, especially when he duels. And is it just her or does his "other side" have an interest in her? Will she become friends with Yugi and Co.? Maybe fall in love?
