[The world view of EVA (slightly modified) + the alien beasts in Nexus (slightly modified) + the monsters in Heisei Sanjiri + the mid-to-late EVA machine "slightly modified" + no system]
Li Wuyou, an "ordinary" exchange student, "accidentally" picked up the Evolution Truster by the river, and then he had a "roommate" named Li Linyuan in his mind.
Next door lives Rei Ayanami, the pilot of Unit Zero, and the genius girl Asuka is transferred to the class.
Apostles are coming, alien beasts are raging, monsters are invading, and three front-line crises are detonating at the same time.
He carefully maintains a balance in the emotional entanglement between the two girls, and also looks for the answer to the fate of the two souls coexisting.
When Ayanami Rei is in danger, Li Linyuan will always take over the body at all costs, even if it burns up.
"You protect her, I'll protect her." This is the silent agreement between the two souls.
