Okay, after some gentle prodding by a number of people and some tantalizing suggestions, I've decided to start a Psyren Crossover with Nasuverse and I need help.
Basic Idea
A Shinji-centric fanfic (with interludes looking into other characters) where upon several side-characters in Fuyuki are dragged into a hellish future where the arrival of TYPE- Ouroboros has begun terraforming the Earth. Gaia is dying while Alayashiki has the Counter Force empower a psychic capable of performing a Leyshift with others and pulling in all those willing from the past to resolve the scenario, subjecting them to a contract and bestowing upon them access to the development of psychic powers (read: engrave specialized circuits to realize supernatural phenomena) called—Drifters.
Drifters need to sift through the events of the future to unravel who it was that beckoned Type-Ouroboros in a bid for power (W.I.S.E) and find a way to kill it in both the past and the future.
Drifters
The drifters are people that were pulled into the future by the events of the story through Nemesis Q. The focus is on the Drifters native to Fuyuki, but people from all over the world have been pulled in. All drifters are bound by something akin to a Geas to Nemesis Q to prevent them from spreading the future knowledge they have. This is done because certain elements (W.I.S.E) would no doubt hasten the effect—this Geas can be broken by Rule Breaker used by Shirou.
Time Travel
Nemesis Q sends the souls of the drifters to the future while their real bodies stay in the present through a contract made when the cards are called. So technically it would be a form of really vivid remote viewing, or future sight ESP, with the soul’s manifestation in the future being something akin to a Servant’s Materialization. It happens in virtually a split-second from normal time, but they can spend days on the other side.
Since the body reflects the soul, if the spiritual body of someone in the future that is Psyren is hurt, the damage will be transmitted to the body in the present explaining why someone can get killed or grow stronger there. Mechanics are similar to the Leyshift in Fate / Grand Order.
Future
The planet the Ouroboros comes from actually died, but instead of just giving up that planet launched it's terminal to space and sent it to Earth as a parasite. What the Ouroboros is meant to do is terraform the Earth into the same planet it came from, basically killing the planet and changing it for a new one (so in the future of Psyren, Gaia is not completely dead, but in the process of being taken over by the will of Ouroboros/the invading planet). The Taboo monsters are the result of it trying to harvest the living creatures on Earth to make it into servants/the new life of the planet that will be born.
World-building: At the same time, Dead Apostles have rallied to defend their food supply, various magical organizations that have weathered the intial advancement have congealed into a single entity to try and deal with it, but the magecraft foundation (Gaia) is damaged extensively—making magecraft something a dying art and some foundations completely eradicated.
Main Characters
Shinji
The perspective character of the story, Shinji becomes a drifter after overhearing rumors from the track girls (the rival one stating it’s no fun competing with her anymore) going around involving Ayako and seeing her withdrawn and unwilling to talk about it (after asking her brother in the archery club). Feeling some remorse after having Rider victimize her, he ends up getting his hands on one of the cards and calling the number to be pulled into Psyren.
After his first trip, he ignores Otoko’s advice to keep it secretive and tries to take to Shirou because this is his sort of thing (and he can’t stand the thought of being around Rin), but he nearly has a heart-attack (the effect of the Geas) in the process. When he wakes up in the Infirmary, Issei is looking over him and explains that he was warned that he can’t speak of it with anyone who doesn’t have a card.
Ayako
A veteran drifter (four trips) that has grown distant from her family due to her constantly being called into Psyren and not being able to discuss it due to the Geas, she still goes to the archery club because it allows her to get away from everything and is something she considers normal though she’s withdrawn. Her brother is also a member of the Archery Club.
Issei
A veteran drifter who was involved before the plot of the story, since the first case of the Sudden Death Syndrome six months after the Holy Grail War. He acts as a sounding board between the Fuyuki group, gathering them together through teleportation before they leave to Psyren and then healing their bodies after they return alive.
Gai Gatou
A classmate of Shinji and fellow drifter at the same time, he got involved because he wanted a card to give to Kohane since he thought it would impress her, being a rumor monger and ended up getting involved. A cheerful idiot and optimist in Shinji’s eyes, when Kane gets drawn into Psyren, he vows to protect her. He later plays up a Gorilla theme.
Kane Himuro
A member of the track-team and their high-jumping ace, she’s a quiet girl who loves rumors and managed to track down a Psyren card somehow, becoming involved in the plot. Her abilities reflect art and healing, allowing her to create landscapes in painting and later Cure.
Otoko Hotaruzuka
Daughter of the owner of Copenhagen and a veteran drifter that completed her run through Psyren, she acts as a mentor to Ayako. She was the one who taught her how to create explosive burst as well.
Reikan Ryuudo
Issei’s brother and a veteran drifter who has completed his run through Psyren, he acts as a fighting mentor to the others and balances out his brother’s desires. He was one of the first drifters at the beginning. He is currently friends with Otoko, trying to get a date with Taiga, and acts as a mentor to Gai.
