though I'm not read previous chapter, I have suggest if you'll rewrite this. How about make MC to transmigrated after Kannabi Bridge's incident. The different is the one who die is Kakashi, so Obito is woken up with Mangekyou.

how about use [World End Harem] plot and put many character in different anime? anime: COTE, Oregairu, Shokugeki no Souma, Roshidere, Gotoubun no Hanauome, BOKUBEN, Saekano, HOTD, etc.

do he already awake his spirit? If he doesn't, I have a suggest. How about make his spirit looks like baby wyvern instead. You know, concept of the dragon rider is interesting.

with that kind of authority (wish that he get Precognition ability, either from spirit ring or spirit bone). Wish that he create his own godhood. Becoming [Time God]

character and plot is well known, so easy to develop 👍

if you can, how about take some character from another anime too. Let's see. Class D: Yukinoshita Yukino, Yuigahama Yui (Oregairu). Class A: Shinomiya Kaguya (Kaguya-Sama Love is War). Class B: Suou Yuki (Roshidere)

Class D 1. get Kei when she ask him about fake boyfriend. 2. Kikyou, when he take video about her real personality. 3. Sakura, found out her idol background. 4. Suzune, in Deserted Island Special Test. 5. Sae, giving rewad after make their class become Class C. Then having blissful life in summer vacation with them + Arisu

suggest harem: Lilia, Zenith, Roxy, Ghislaine, Elinalise

how about make it as a long sword with light weight (the appearance is similar with Trafalgar Law's sword). Sword's ability is extreme sharpness.

if it still Nasuverse, how about become being Matou Shinji, set his origin as curse. Earlier story is about enlsaved Sakura (also having medusa in his hand). Medea will make contract with him instead Soichiro and than call Assassin (Hassan if Serenity). Taking Saber from Shirou with Ruler Breaker. Kill Archer then claim Rin. Next target is Cu Chuliann's master, Bazzet. The last is defeat Berseker and Take Einzbern. The Obsever will be Caren Hortensia.
