If you can be a light, you will pierce the darkness.
Don't be misled by the blurb. The main pairing is 02, and the Crest of Light still belongs to Hikari. The female lead has a huge advantage, so don't read if that's not your thing.
The female lead is genuinely highly intelligent, a genius, but only in terms of intellect. She's more mature than her peers, not a perfect character.
The female lead is extremely overpowered, so overpowered that she can change the plot.
But she's not a Mary Sue. She does have a tendency to be adored by everyone, but that's only because they're all good kids and she's physically weak, so they look after her.
I won't vilify anyone. Everyone is a good kid, including the female lead.
No one is reborn or transmigrates. The female lead is a native, Daiki's twin sister. Due to the butterfly effect, Daiki will be a little more mature, but not so much that he seems like a completely different person.
The female lead probably won't have a love interest. There are some Ken x Takeru and Tai x Yamato tendencies, so don't read if that's not your thing.
Written for love, updated whenever inspiration strikes, not contracted.
Theme: If you can be a light, you will pierce the darkness.
Awesome, love it, love it
