Britain is not just one Touhou, Moerin.
England is Kaguya. Self-important and convinced of her own power, even though the time when she actually ruled is long past.
Scotland is Mokou. Trying over and over again to escape from England's shadow, but England refuses to give way.
Wales is Reisen. Different enough that its culture is respected, but otherwise uninteresting.
Ireland is Tewi. A tiny part of it still gives in to England, but for the most part its independent and refuses to be governed by the folks at number 10.
