東方実在相 ～ Dream Logical World/设定与剧情/故事背景

Gensokyo: the land of fantasy where things go when people stop believing in them.	幻想乡，被人们否定与忘却之物会流入的幻想之地。
In late autumn, a gentle sense that something was off gradually emerged in powerful spell card users, like the shrine maiden Reimu Hakurei, the magician Marisa Kirisame, and the youkai of boundaries Yukari Yakumo. But they didn't feel any compulsion to investigate. What exactly was off? Nothing they could name on command.	某个晚秋，以巫女博丽灵梦、魔法使雾雨魔理沙、境界妖怪八云紫为首，解决异变的专家们感受到了一丝“违和感”。 但是，她们却没有一丝一毫想去调查的冲动。 对于究竟发生了什么，她们也一知半解。
At least for Reimu, there was no visible reason to worry. The Hakurei Shrine was having yet another profitable day, with worshipers and donations arriving at a steady pace. Observing this, Yukari finally realized what was wrong.	不过，至少对于灵梦来说，她似乎并没有什么必须要担心的理由。 今天，就像往常一样，博丽神社赚得盆满钵满，参拜客和赛钱稳定地涌向神社。 观察到这个的紫，终于发现了违和感的源头——
Heading down to the shrine, she asked Reimu "Doesn't your shrine hardly ever get visitors or donations?" "Yes, but..." The correct answer having effortlessly come out, Reimu stopped her sentence dead in its tracks. "Then why are so many here?" Examining her memory further, she realized she hadn't even taken note of the Hakurei Shrine going from desolate to overflowing, and couldn't remember when that had happened. "Wait, what? What's going on?!"	紫 「灵梦，以前你的神社有过这么多参拜客和赛钱吗？」 灵梦 「当然有啊，不过……」 理所当然地说出这句话的灵梦，突然沉默了下来。 灵梦 「诶，为什么会有这么多参拜客呢？」 回顾了记忆，她突然意识到，她从未奇怪于博丽神社突然从门可罗雀变为摩肩接踵这件事情。 甚至，她不知道这件事是在何时于不知不觉间发生的。 灵梦 「等等，到底发生了什么？」
The word spread, and soon no one could make sense of their own reality.	随着灵梦的调查，这件事传播开来。 渐渐地，大家发现，没有人知道，属于她们的“真实”是在什么时候被悄然替换的。
"Since when did these purple trees have diamonds growing on them?" asked Marisa. "Since when was the path from the Human Village to the Hakurei Shrine this short?" asked the moon rabbit Reisen Udongein Inaba. "Since when were people displaying such strong kinship and empathy?" asked the satori Koishi Komeiji. "Since when did the library have these reflective beams built into it?" asked the young bibliophile Kosuzu Motoori.	魔理沙 「这些紫色的树上竟然结满了钻石！」 铃仙·优昙华院·因幡 「人类村落到博丽神社的道路，什么时候变得这么短了？」 古明地恋 「最近的这些人类，怎么变得异常地亲切与热情了呢？」 本居小铃 「借书屋的大梁上，以前有贴着这些反射材料吗？」
It was as if all of Genokyo had fallen asleep and woken up in an alternate reality—a world of dream logic. The mind always wants to believe what it's seeing is real. In a dream, it will rationalize even the most absurd circumstances, so that one will almost never realize they're dreaming. By recognizing points of contradiction where their reality didn't make sense, the denizens of Gensokyo were able to discover they'd been living in a dream-logical world for some unknown but significant length of time.	魔法使，月兔，觉妖怪，爱书人。 似乎所有幻想乡的居民，都在现实中沉眠，而在梦论理 (dream logic) 的世界中苏醒了。 人们的意识，总是相信着“所见即为真实”。 所以，就算在梦境中，最为荒谬的事物都被视作合理，她们也不会意识到她们正在梦境之中。 但是，通过指出与她们难以意识到的现实中的“真相”互相矛盾的地方， 幻想乡的住民们终于意识到了，她们已经在梦论理 (dream logic) 的世界中生活了一段未知但重要的时间。
No one could be sure that anything about reality was the way it had always been. What aspects of their existence were "real", and what had recently been altered? Calling memories to the surface, themselves distorted by dream logic, was the only way to piece it together. Gathering in teams, the spell card users set out to uncover the truth...	没有人能够确定真正的“真相”究竟是怎么样的，也没有人能够明白何为真实，而何事已被篡改。 为了揭露被梦之论理扭曲的“真相”，结伴出发的解决异变的专家们，为了找回记忆出发了……
