ideas for books

I wanted someone to have both the sunshine magic that escanor has and the acess to darkness and hellfire from demons from the seven deadly sins universe. I MAY give mc a "seven deadly sins" system, and have mc eventualy get the powers of all seven sins, but i think that would be way too much, i think i will give mc just escanor's powers, have him get reincarnated as a devil, and have him recreate the demons' darkness with the devil's imagination magic(also making a sunlight storage with magic, so mc can both transform at night and not transform during the day if they so choose), i think i will give mc those sealing glasses at the start so mc can have a normal life without having to sneak into a desert every morning and stay there till sunset(i just noticed, but i think escanor dosen't need to sleep, lol)

I want mc to get killed by raynare instead of issei(or maybe a day or so before issei and therefore rias won't have enough pieces to reincarnate issei), mc would just be buying groceries or something at night and be lightspeared in the back(i don't think i will give mc a sacred gear, raynare may have just killed a random for funsys), rias shows up because raynere forgot to put up a barrier and rias sensed the light magic(bs, i know, but i needed a reason for rias to be there), rias reincarnate mc with a single pawn piece(it was night, so the power required to revive mc was low as heck). Because raynere was outed, she dosen't even do the date thing, she just break into issei's home and kill him, when rias find out about issei's death the next day, she also tryes to reincarnate him, but she is unable to, she chalks it to her just beeing too late, in truth, she just diden't have enought pawns, but she won't ever learn of that, mc the next day does wonder if it had been a dream as mc had never seen signs of the supernatural existing in the world he reincarnated to so far, but a look on the calender did confirm it was the next day, a look in his fridge also confirms he got the groceries, mc decides to investigate, taking advantage it was daytime, mc goes to where he remember he was atacked, a hand griping the side of his glasses all the wile, ready to take them out at a moment's notice should he be atacked from the back again, mc runs into donaseek, donaseek goes on his speech about killing strays and prepares to atack mc, mc takes off his glasses and quickly kills donaseek(maybe i will have mc have rhitta(escanor's axe) as a soul bound weapon(having to make rhitta fly all over the place is akward, so beeing able to just store it inside your own soul makes things much more pratical))
