History GranblueFantasy / TropesDToH

* EveryoneIsBi: has, with a few exceptions (Metera, who is straight, and Sandalphon and Vira, who are very deeply in love with a man and a woman, respectively), everyone be bisexual, or at least not explicitly leaning either way. Some of this is due to the player character of either gender being able to participate on both sides even in gendered holidays (Valentines and White Day are both gendered in Japan, with the latter even existing because of it), but many of them show interest in both sexes. In a rarity for fiction, the characters also have preferences for which gender they prefer, even having their lines changed depending on whether you play as Djeeta or Gran if it applies to them.

* ForWantOfANail:
** The Miscolored Memories events depicts in [[spoiler:a nightmare created by Oneiros]] what happens if Gran/Djeeta dies without Lyria reviving him. Katalina and Lyria are constantly on the run, always fearing for their lives while Rackam, unable to fix the Grandcypher, remains stuck on Port Breeze for the rest of his life.
** Lady Katapillar's introductory Fate Episode is based around Vira getting the upper hand in the "L.E.T'S. H.A.N.G." event.
** The Titanic Yeager event is this for Manga/AttackOnTitan where [[spoiler:the crew finding themselves in Estioss led to a chain of events that gave the cast of Manga/AttackOnTitan a hope for freedom. In the ending of this event, the Shingashina trio are sent off to travel with the crew as a form of expedition and Levi joins along to keep watch of Eren.]]
** Justice's pact with Maria Theresa involves finding the answer to a question among the lines of "What if a powerful being capable of changing history dies before they can fulfill their role?". And as to Invoke this trope, Justice notes that the Singularity is one of those beings.
** The ''Franchise/CodeGeass'' collaboration event, "Code Geass: Lelouch of the Rebellion - The Blue Reckoning" has one where Lelouch, C.C, Suzaku and Kallen are taken to the Granblue Fantasy universe before [[spoiler:Euphemia's death and deciding to stay in the Granblue Fantasy universe at the end of the event. Granted, they still have plans to find another way back home, but the fact that Suzaku and Kallen are aware of Lelouch being Zero, and having plans to willingly cooperate with each other, has the potential of changing ''many'' things that are to come in their home series]].
** "And You", the 9th Anniversary event, is built on this trope. [[spoiler:Orologia, the Wedge of Causality, created many simulations in order to find the one timeline that would ensure the MC and the crew survived. Naturally, as it's with stories based on this, it shows what would happen in different scenarios caused by specific choices or luck.]]

* HighSchoolAU: Lowain, Elsam, and Tomoi come up with one in the "L.E.T'S. H.A.N.G." event where the former two are students and the latter an instructor at Albion Military Academy. It's noted that due to it being a fantasy of theirs and not having the full details from Katalina, there are discrepancies from reality. The "Table for Six" event adds Sutera and Korwa as students and Isabella and Jin as faculty members.
