To have a relationship with Grayfia, I think it would be possible even if she doesn't join James' peerage as queen and you would have to trade pieces with Sierchez, which can be a bit tricky, but if you find a way for Sierchez to trade pieces voluntarily, then it would be fine. If the above doesn't work, Irine would be a very good option and if you can accompany her with Erza and other Fairy Tail girls it would be even better xD. Nobility with Grefia: Queen - Grayfia Tower - Kuhlúa Tower - Akua Bishop - Irine Bishop - Evangelina Knight - Erza (Dragon Blood Lineage) Knight - Miyamoto Musashi Pawn - Kurama x2 (or 1) Pawn - Hiei x2 (or 1) Pawn - Kokoa x2 (or 1) Pawn - Kagura Mikazuchi x2 (or 1) Nobility without Grayfia: queen - irine Tower - Kuhlúa Tower - Akua Bishop - Evangelina Bishop - Chisato Hasegawa (Fallen Angel) Knight - Erza (Dragon Blood Lineage) Knight - Miyamoto Musashi Pawn - Kurama x2 (or 1) Pawn - Hiei x2 (or 1) Pawn - Kokoa x2 (or 1) Pawn - Kagura Mikazuchi x2 (or 1) I think you could change all the humans that are not reincarnation of heroes or have blood from other races to Pawns, since humans usually don't have a characteristic trait I think it would be good if they were pawns, so I put Hiei and Kurama as pawns and I added Erza with dragon blood for being Irene's daughter when she was a dragon and it would be a good power for Erza. It would also be nice if all the Shuzen sisters join the MC nobility and I'm not sure how many pieces the MC needs for the pawns so that part may be wrong and sorry for the long comment, I had many ideas, although these are just suggestions.
Adding to those that the author already has in mind and only suggesting with which pieces it can be reincarnated, in addition to other characters that I consider interesting to occupy the other pieces, I think it could be like this: James's Second Peerage: ▪︎James Alaverus - King ▪︎Irene Belserion - Queen ▪︎Kuhlúa Shuzen - Rook ▪︎Akua Shuzen - Rook ▪︎Evangeline A.K. McDowell - Bishop ▪︎Kurama - Bishop ▪︎Hiei - Knight ▪︎Erza Scarlet - Knight ▪︎Roe2 - Pawn ×2 o 3 ▪︎Zazie Rainyday - Pawn ×3 ▪︎Nezuko Kamado - Pawn ×3 o 2
Irene as the queen, the sleeping leviathan girl(Ingvlid leviathan )as bishop, Rossweisse can be traded, Bennia orcus as his knight, Then there was Ruby tojo from Rosaria vampire series take her as a bishop, Erza as his knight, Mirajane as his rook, leave Lucy out I ship her with Natsu, You can cook up some story about rescuing Medusa and make her his pawn or rook, same with other fate characters you can probably cook up some stories and fill his peerage
Well I would give Kahlua either a rook to strengthen her super strength and up her durability or go with knight to add speed to the power to make her an evasive power type fighter. Evangeline should be either a bishop to strengthen her magic, which is versatile and balanced, or give her pawns to be more flexible. Grafia must have had a loooooong build up to come to this point in the story. So any quick redemption of Sirzechs is impossible. He is basically a drug addict. Pride is his drug of choice and not the good part, but the most horrible of it. He can go one of 2 ways. 1) the loss of Grafia hit him out of it and he pulls his head out of his a*se. Build himself back up from the ground, ie kills of his pride, starts training again, cut himself off his family for a while, doing the right things and not the easy or popluar things like before and after he did all that come back changed for the better. 2) He spirals down and becomes an antagonist. As for if Grafia should become the queen of his second peerage, I think so. She saw James growing up and never going the easy way, but for what he thought to be the best way, no matter the burden it placed him under, ie what Sirzechs should have done. If you ask for harem member or not that´s a bit of a toss up. On the one hand James is basically what Sirzechs would be idealy. Powerful, thinks of the wellbeing of the devils as a whole, kind, having an overall rounded point of view that takes many things into consideration before acting and having his sin under control, with so many anchors to ground him to be a stable leader. On the other hand he is her "little brother" whom she saw growing up. That is hard to change, if nothing crass happens. Like James actually persueing her, which he more likely then not wont do.
