it seems interesting. this is just my opinion, since his spirit will be True Longinus, how about make to possess just Ultimate Light. Also, since Shen Ming and Hui Mei as parents. Set it give him unstable bloodline (Life and Destruction in his bloodline is clash each other due to divine energy) as reason to send him to lower realm. Have multiple seal like Wulin's GDK. So, instead Light and Darkness. I think Light of Live and Light of Destruction will be better.

I think that introduce as Spiritual Sharing as spirit ring ability and Spriritual Detection as innate skill more suitable

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
