Let me tell you why stage 4 of WBaWC is one of the best Touhou stages of all time and one of the many reasons WBaWC is my favorite game in the series.

>last hell appearance was way back in HRtP, the first 2hu game
>know hell still exists in PoFV but only ever see Sanzu River
>former hell is introduced in SA, which makes you wonder "what the fuck does current hell look like?"
>WBaWC, your enemy is supposedly on real current hell
>go to Sanzu River from PoFV and encounter Kutaka, who even references my hero Eiki and says she wants to test you based on PoFV events
>stage 4 starts and you're finally in hell
>kino guitar riff and a barrage of enemies welcome you
>in sync with the song's drop (one of the best songs ZUN has made btw), the background reveals a bunch of skulls and Yachie enters, welcoming you to hell
