Magia Record 6th Anniversary ARG
On August 18th, 2023, the Magia Record X (Twitter) account posted a link to a webpage on their site: https://6th.anniv.magireco.com/ . Its primary features were a countdown for the game's anniversary's announcement (which was to occur on August 20th, 2023, 18:00 JST), an announcement of an Amazon giftcard campaign and a button to share the campaign on X.
However, the page also contained three clues:
- A code on top of the page, that reads eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.
- After base64 decoding, it reads {"alg":"HS256","typ":"JWT"}
- A code in the middle of the page, that reads eyJ1cmwiOiJodHRwczovLzZ0aC5hbm5pdi5tYWdpcmVjby5jb20vc2VjcmV0LyJ9.
- After base64 decoding, it reads {"url":"https://6th.anniv.magireco.com/secret/"}
- A code at the end of the page, that reads [1:][2:][3:][4:][5:][6:][7:][8:][9:][10:][11:][12:][13:][14:][15:][16:][17:][18:][19:][20:][21:][22:][23:][24:][25:][26:][27:][28:][29:][30:][31:][32:][33:][34:][35:][36:][37:][38:][39:][40:]
The X share campaign button randomly picked one of 90 pre-fabricated tweet formulas, which only differed by the featured link. The link contained a simple image featuring one of Magia Record characters[1], the game's logo, the name of campaign, and a code. The codes duplicated between some characters. The codes read:
1: O 2: 4 3: W 4: 7 5: T 6: w 7: h 8: x 9: Y 10: i 11: e 12: U 13: U 14: 8 15: F 16: F 17: D 18: P 19: W 20: v 21: 4 22: F 23: p 24: k 25: K 26: n 27: q 28: m 29: z 30: R 31: t 32: l 33: 6 34: T 35: E 36: p 37: p 38: s4 39: dG 40: WA
Combining to O4W7TwhxYieUU8FFDPWv4FpkKnqmzRtl6TE9ps4dGWA .
The hamburger menu on the main page additionally had a link to the setToken page: https://6th.anniv.magireco.com/settoken/ . After entering the three codes combined (eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1cmwiOiJodHRwczovLzZ0aC5hbm5pdi5tYWdpcmVjby5jb20vc2VjcmV0LyJ9.O4W7TwhxYieUU8FFDPWv4FpkKnqmzRtl6TE9ps4dGWA), and entering the /secret/ page discovered from the second code, an ASCII artwork of Homura's shield with the number 6 appears:

The ASCII artwork can then be further base64 decoded into a small image of Akuma Homura's symbol after removing the spaces and linebreaks.
- ↑ All Magia Record original characters which had units released up to that point had their own pages, with exceptions for characters who died, were first introduced in the anime, or the Puella Historia series of events. Additionally, no alts were featured.
