@venti_supremacy08 timelines are the worst to figure in absence of a clearly defined one (which often happens in manga/webtoon since that's not the focus and it takes enough time to set up the drawings and storylines), I think I got wrong by a week maybe in Réka's arc (I caught up the mistake in Tenko's/0, and... that's main reason why I set most of the story outside of canon (6 years before war, 10 years after) so I get a wider range to set it (and also because these ones were relevant enough). I don't really transcribe, mostly using MBTI to make characters speak (Tomura, main MHA OC, is INTP so oh damn easy to get). Waiting until end of canon was a wise decision if you aim for a canon-compliant fic since, well that fits better then (I understand if some elements diverge, many stories do that, then you have those who slightly diverge but stay faithful and those who treat MHA as a sandbox). I'll save your story for later so I'll be sure to have it marked somewhere!
