Who are the characters infected for each?
1st: Jake
2nd: Michael
3rd: MC (Father)
4th: MC (Mother
5th: Zaman
6th: Nico, Alice
7th: Valvarn
8th: Tiffany
11th: Moon Bro
12th: Moon Sis
Am I missing someone? Did I get anything wrong?
Also, what's the difference between the electric monster that Michael fought and the being that descended from the skies to give him the power. Is he the only superhuman (that we know of) who had direct contact with such being to gain those powers?
Zack Zaman might not be directly infected by the 5th. Deus is also from the line of the 5th. The new character from this update Halona is as well, but it's likely the 5th isn't any of their direct parents.
Nico and Alice aren't directly infected by the 6th either. Alice has the fairy as her parent and the 6th is her grandparent. Nico was infected by a Hexenringe, which is a lower generation monster.
The known characters directly spawned by the Apostles are Jake, Michael, Ella, MC, Tiffany and the Moon Twins.
Valravyn is a monster so is a bit different than the superhumans, but is a direct spawn and has the pure trait of the 7th.
The Blue Fairy is a direct spawn of the 6th and has the full trait, which it passed on to Alice.
Both the 3rd and the 4th have proclaimed the MC as their heir, regardless of which is his true parent, and this update showed that they thought Ella was flawed and refused to accept her as their heir.
Alice was told by the 6th that if she kills the Blue Fairy she will be the heir of the 6th.
Jake also seemed to be the chosen of the 1st when he was taking over the prime ministers office, but he might not be anymore.
We don't really know what being the heir or chosen of an apostle means.
The electric monster that Michael originally called was several generations descended from the 2nd and wasn't an Apostle.
Michael wasn't infected by that monster and instead killed it, which allowed him to give it as an offering to the 2nd which then infected him.
Edit: I took too long writing this, and Drako pretty much already gave all this information and more.
