It's also the only Game Over screen to actually tell you, in exact uppercase words, "GAME OVER". No poetry, just bluntly telling you that you've failed.
As scary as this sequence is, Devil Summoner Soul Hackers for the 3DS has a bonus scene when Raidou appears that expands on it. He makes mention of the "scolding room" after you beat him for the first time, implying that it's happened to him before. Whether one'd consider this Canon or not, the idea of the outcome being a mere verbal dressing down before being sent on his way again really takes the oomph out of it.
The Hiruko are monstrous parasites born by the unnatural alteration of humans who experience crippling fear or hate, and just sooo love bursting out of their hosts. Eventually, you find a large radio tower responsible for their creation. In the normal world, there is nothing particularly strange about the tower. In the Dark World? The Tower is coated with immense blobs of Hiruko.
When you finally corner Munakata, he makes a final attempt at stopping you with words, which obviously fails. Munakata's eyes then roll back and his mouth opens wiiide... revealing the tiny Puppeteer Parasite Sukuna-Hikona, who's been driving Munakata's corpse for months.
Raidou the 14th! This is shameful. You have disappointed us. Your wiki edits are pathetic compared to the ones who preceded you! It was a grave error for you to Get Known as the 14th Raidou Kuzunoha. We have no choice. You've slandered the sacred name of TV Tropes. Begone!
