[li]OG gang (Clair, Elena, Kaito, Honoka, Aiko, et al) meet at cram school[/li]
[li]Alien comes around, meets Honoka, starts the coins for mutations business[/li]
[li]Aiko and Honoka "merge" (one dies, the other gets super advanced plastic surgery to replace the dead one). [/li]
[li]This is the start of a spiritual anime mumbo jumbo that could be behind the series title. It might be the most confusing thing besides Elena's memory jumbling. Basically, Aiko was depressed, but had a good life. Honoka had a shitty life, but just a bit more will to live. Aiko committed suicide. Honoka saw a chance to restart her life AND continue the awesome adventures of Aiko. SOMEHOW this means that Aiko's public life (as a concept perceived by others) overwrote Honoka's personal life (as a concept perceived by Honoka). Public + personal... Honoka gave up her damaged public life, and willingly let go of her personal life. This is what she had meant with her last words to Kaito. "There's barely anything left of her."[/li]
[li]Kaito gets the wrong idea and ruins everything by killing the Aiko/Honoka entity. Communication is important you guys. Now all public and personal facets of Honoka's and Aiko's lives have been destroyed.[/li]
[li]Kaito turns into an immortal necromancer god and revives Honoka. It gets real tricky here. If the alien can be viewed as a scientific metaphor (needed DNA samples and raw material to recreate Honoka), the humanity can become a spiritual metaphor. The alien could make a Honoka-like body, but he could not remake her soul. He's from a race that equates a soul to "information" which can be turned to semi-physical objects - coins (they cannot be seen by cameras implying their spiritual nature). What was created was a person with a void for a soul/life/something metaphysical because the alien could not fill it, and Kaito made sure there's nothing to put there.[/li]
[li]Honoka 2.0 hates the world and inexplicably has a power of localized Thanos Snaps.[/li]
[li]Honoka 2.0 starts snapping people with "connections" (referenced in manga and anime)[/li]
[li]Rest of the gang get coins to fight against Kaito and Honoka 2.0[/li]
[li]Honoka 2.0 kills Clair and Elena's and Shuichi's parents (implied in manga, shown in anime)[/li]
[li]Elena and some others splinter off from the gang to keep collateral damage to aminimum in their fight. Oh the hubris of that solution...[/li]
[li]Memory fuckery[/li]
[li]Shuichi rescues Clair (chapter 1)[/li]
