A Spell Card of Reimu Hakurei, who has almost reached the end (a Touhou LW original). She prays solemnly and attacks.

The Borders of Gensokyo
The Great Hakurei Barrier is the most well-known barrier in Gensokyo, but it's far from the only one. The others, such as the barrier between illusions and reality, also help separate Gensokyo from other worlds. There are clear restrictions for who or what can pass through certain barriers. For example, the souls of the dead can pass through to Higan, and items lost in the human world can pass through to Gensokyo. However, these restrictions can be bypassed by a few select individuals.

It's said Hakurei Shrine was built on the border of Gensokyo and the outside world, but supposedly, it's more like the Hakurei Shrine of Gensokyo and the Hakurei Shrine of the outside world are located in the exact same spot. Reimu lives in the Gensokyo Hakurei Shrine, and despite her inability to gather faith, with her living there, the shrine is able to function. The outside world Hakurei Shrine, on the other hand, is said to be empty and desolate. However, according to Rinnosuke Morichika's records, he saw the outside world shrine bustling with people who seemed to be celebrating some kind of festival. But he still hasn't been able to verify whether the things he saw were real or an illusion...

Reimu does sometimes find unexpected, mysterious offerings in Gensokyo's Hakurei Shrine. Assuming those offerings have drifted in from the outside world, then perhaps its Hakurei Shrine isn't completely empty...
