Hybrid Precure:The Last Hope (Info Book)

Hybrid precure series timeline(how old would they be?) Part 1

*HEAVILY INSPIRED BY SECOND ROUND*

A few points to note:
1) This fan series mainly uses the Love anime series timeline, which makes things easier to tie in critical points like μ's taking off and becoming popular when Chika was in its first year and the movie taking place at the same time as Love Live Sunshine Season 1 Episode 1-5

2) With point one in mind if I were to put it according to their birth year and ages (next part), I'm going to when the last episode of their respective anime is released. The only exception is Nijigasaki since its two seasons only take place for a year in retrospect. (Season 1 of Nijigaku takes place in the summer while Season 2 of Nijigaku takes place in the same year but in the fall to winter time) (The year baseline is after this set of rules)

3) While making use of the Love Live Anime timeline as the base, the Pretty Cure timeline will be used as well. This means that the very first Pretty Cures took place in 2003 and every year there will be a new Pretty Cure that will be debuting. The only exception is this:
a) Since Maho Girls Pretty Cure and Kira Kira Pretty Cure Ala Mode take place in the same world, it would make sense for Cure Whip to debut the same year Mirai, Liko, and Hanami from the previous series reunite, which is five years later. Making their appearances in Dream Stars, Huggto Precure episodes 36-37 and Precure Miracle Universe look like they are the juniors instead as the Huggto cures had sawn their future selves. This means that the present Kira Kira Cure does not know about the Huggto and Star Twinkle teams at all.
b) While out of the Pretty cure category, it also applies to the Pokémon anime timeline since a Pokémon generation lasts for four years.

4) To make things accurate to real-life history as well, the Thomas and Friends timeline will take place in the 20th century in parallel to Love Live and pretty cures' 21st century. (This means 1910s to 1960s) This is because steam railways are popular at that time and gives a contrast to when it becomes a key moment in history.
a) it also applies to the Covid Pandemic since in real life it took place for two years now, so in this Au, the pandemic only took place in 2020 and things start to get better in 2021. 

5) Although the time in Oshi No Ko is canonically unknown, details show the time the show takes place. Examples would be the phone screens and phone details.
