Concluding the Vocaloid series is the second last question of the game, and also the hardest one. This question comes from arguably one of the most obscure knowledge in the entire game – lyrics of cosMo’s songs. In some of his songs, cosMo puts the notes or chords of the humming parts into the lyrics, and I found it quite unique.

Aiming for the most difficult question in the game, putting the lyrics verbatim would be too easy, so I decided to trim off the “Ah” parts, keeping only the musical notes.

Ah---(G) Ah---(B♭△)
Ah---(D) Ah---(Dm7)(G7/D)
G B♭△
D Dm7 G7/D

A comparison of the original and the trimmed lyrics of θθしにたがりにつけるくすりθθ.

On the answer, using the song name is not an option due to the non-ASCII characters within them, and encodings would reveal the song name too easily. Video URLs could also be confusing as the songs are spanning over a decade, and the platform uploading them varies. The next option I went for is to find a database that has a collection of all of them. Fortunately, there’s VocaDB. I put the ID of the original version of each song as the answer. Luckily, it is not hard to find the relationship between them once you have any two of the three hints: the song name, the ID, and “VocaDB”. So that I didn’t make it too hard.

However, unfortunately, after trimming off the “Ah”s, search engines seems to have a hard time figuring out what to search for, even with the characteristic “B♭△”. The only search query I manage to find working (as of Sept 2021) is "G" "B♭△" "D" "Dm7" "G7/D" "C", which featuring a search result about the song.
