Yugioh should be made into a show like GOT. We got Egyptian princes, we got political unrest, we got royal family inner conflicts, we got dragons, mystical monsters and magic! Minus the nudity and sex scenes ofcause, i dont think i could handle seeing that….
When I saw Kisara’s silhouette shown in Kaiba’s eye in the second picture, a thought came to my mind: Kisara is where Atem is, meaning Duat, the world of the dead. And for the dead to be there, according to @kaleidraws’s post, one need all their parts — Ka (essence), Ba (personality), Sheut (shadow), Jb (heart), and Ren (name) — and a priest doing all the necessary spells and rituals to receive judgement from Anubis and, if determined a good person, to spend eternity happily in the afterlife. In other words, for Kisara to still be a spirit even after around 3000 years, Priest Seto must have fufilled all the requirements to give her a proper burial. Manga!Priest Seto is undeniably more twisted than his anime counterpart, but I find it beautiful how he ensured that Kisara would have a comfortable afterlife.
(If Takahashi had had more time, he would have given us the relationship worthy of those lines.)
There’s also a certain tragedy to it. Because Priest Seto had to ensure Atem would get the eternal rest he deserved, he probably died without giving himself a proper burial so that he would reincarnate (which can be said the same for Isis and Shimon/Siamun). And knowing Kaiba’s refusal to acknowledge the connection between him and his past Egyptian life, I doubt he would follow the procedure of an Egyptain burial. This means he and Kisara will never be together and are only so as Duelist and Monster / guardian spirit.
