【Answers and Explanations by Mystery Designer】
First, solve Q1~5 published in the booklet while gathering information about 'conditions for the person used in the mystery' displayed at each store.
By sending answers to LINE, you'll get one alphabet letter per correct answer.
Q-1-1
The condition for the person used in this mystery is 'a person whose name contains hiragana'
Within Ave Mujica, 「Yutenji (ゆうてんじ) Nyamu」applies.
Connecting 「ゆ→う→て→ん→じ→に→ゃ→む(→ゆ)」 among the pink characters and reading the characters within from left to right, the answer is 「Kumamoto (くまもと)」.

Q-2-1
The condition for the person used in this mystery is 'a person who sings'
Within Ave Mujica, 「Misumi Uika (みすみういか)」applies.
Going through the maze passing through only 「う→い→か」 and reading the red characters of that route backwards becomes 「memories are the answer」.
The answer is 「memories (おもいで)」.

Q-3-1
The condition for the person used in this mystery is 'a person with black hair'
Within Ave Mujica, 「Yahata Umiri (やはたうみり)」applies.
Among the blue characters, the kanji contained in or associated with the name is 「sea (海)」.
Connecting the water radical and the character for 'every' to create 「sea (海)」 and reading the characters in between from right to left, the answer is 「trust (しんよう)」.

Q-4-1
The condition for the person used in this mystery is 'a person who is good at acting'
Within Ave Mujica, 「Wakaba Mutsumi (わかばむつみ)」applies.
Looking at the hint, 「one 2」 is 1 and 「two 2」 is 2.
Likely '2 = tsu', and considering that 3 and 6 have the same font as hints 1 and 2, it can be thought that they might be connected in the pattern one, two, three... six.
Then, '1 = mu, 2 = tsu, 3 = mi'. It was representing the number of characters in the name.
Applying this to the end, it becomes like the diagram.
The answer is 「mirror image (かがみうつし)」.

Q-5-1
The condition for the person used in this mystery is 'a person who plays the piano'
Within Ave Mujica, 「Togawa Sakiko (とがわさきこ)」applies.
Looking at the hint, 「ika」 has become 「ao」 and 「kishi」 has become 「kasa」.
This is one character back in the Japanese hiragana chart.
Going 「Sakiko」 back by one becomes 「kokake」. Adding a dakuten at the end, the answer is 「shade (こかげ)」.

The Final Problem - 1
If you solve all the puzzles up to this point, you'll get the alphabet letters below.

At the final location, there was a poster with marks like this.
Looking closely, there are arrows.

Assigning characters to Ave Mujica members in this poster and reading the characters from right to left like the arrows
The final answer was 「TRUTH」.

When you enter this answer, you receive a message like this from the official LINE.

After that, taking the ticket displayed below to the exchange location at the final point and obtaining the special item, the Ave Mujica Mystery Rally ends.
Great job!
From here on, you needed to notice a certain 「sense of incongruity」.
It is the clear screen from earlier.

For an event named 『Ave Mujica Mystery Rally』, would there be a need to specifically say 「Ave Mujica Course」?
It's a phrasing as if saying you chose the 「Ave Mujica Course」 among several courses.
Looking at it with suspicion, there were strange points in the poster used in the final problem.
Earlier we solved the mystery using the Ave Mujica part, but looking closely

You can see that other bands/units also have arrows.
In other words, what we can understand from here is that this puzzle rally definitely has courses for bands/units shown on the poster other than the 「Ave Mujica Course」.
Thinking so and looking back at problems Q-1 to Q-3, there should be sudden discoveries.
Q-1-2
The condition for the person used in this mystery is 'a person whose name contains hiragana'
If not limited to within Ave Mujica, this condition also applies to 「Nagasaki (ながさき) Soyo」.
Connecting 「な→が→さ→き→そ→よ(→な)」 among the pink characters and reading the characters within from left to right, the answer is 「black tea (こうちゃ)」.

Q-2-2
The condition for the person used in this mystery is 'a person who sings'
If not limited to within Ave Mujica, this condition also applies to 「Takamatsu Tomori (たかまつともり)」.
Going through the maze passing through only 「と→も→り」 and reading the red characters of that route backwards becomes 「humans are the answer」.
The answer is 「humans (にんげん)」.

Q-3-2
The condition for the person used in this mystery is 'a person with black hair'
If not limited to within Ave Mujica, this condition also applies to 「Shiina Taki (しいなたき)」.
Among the blue characters, the kanji contained in or associated with the name is 「waterfall (滝)」.
Connecting the water radical and the dragon character to create 「waterfall (滝)」 and reading the characters in between from right to left, the answer is 「discovery (はっけん)」.

If you do so, the answer to the final problem also naturally changes.
The Final Problem - 2
By combining the alphabets of Nagasaki Soyo, Takamatsu Akari, and Shiina Riki with the alphabets of Wakaba Mutsumi and Toyokawa Sachiko obtained from the Ave Mujica course, we were able to obtain alphabets for all members of CRYCHIC.

Then, by filling in the location characters of CRYCHIC on the poster at the final point and reading the characters from left to right like an arrow,

The final answer was 「ROUTE」.

Furthermore, this was not the end.
In fact, there was only one person who could satisfy all the conditions of Q1-3.
That's right, at the very bottom of the poster. It was Sumita Mana of sumimi.
When we applied her name...
Q-1-3
The condition for the person used in this puzzle is 「someone with hiragana in their name」.
「Sumita Mana」also contains hiragana, so of course it applies.
Connecting 「す→み→た→ま→な(→す)」in the pink characters and reading the characters from left to right, the answer is 「あいどる(アイドル)」.

Q-2-3
The condition for the person used in this puzzle is 「someone who sings」.
Since sumimi is an idol unit, 「Sumita Mana」naturally also sings.
Going through the maze such that we only pass through 「ま→な」, and reading the red letters on that route in reverse, we get 「あいどるがこたえ」.
The answer is 「あいどる(アイドル)」.

Q-3-3
The condition for the person used in this puzzle is 「someone with black hair」.
「Sumita Mana」also has black hair, so of course it applies.
Among the blue characters, the kanji contained in or associated with the name is 「玉」from 「すみ”たま”な」.
Connecting 「王」 with the punctuation marks of the problem text which were actually blue, and reading the characters between them from right to left, the answer is 「あいどる(アイドル)」.

In this way, since Sumita Mana could satisfy the conditions for all three questions, it was possible to come up with a common answer for all of Q1-3.
And we obtain three alphabets for three questions.

Final Problem-3
By combining Sumita Mana's alphabet with the alphabet of Sankaku Hatsuhana obtained from the Ave Mujica course, we were able to obtain alphabets for both members of sumimi.
Then, by filling in the location characters of sumimi on the poster at the final point and reading the characters from left to right like an arrow,

The final answer was 「HERE」.

When the number of players who reached the answers of these separate courses exceeded a certain number, the following image was posted from the official BanG Dream! X.
https://x.com/bang_dream_info/status/1914162256486752715
Looking closely at the dark parts, we can see coordinates and dates written.
When we searched for this, the following locations and dates came up.
• 4/26-27 K Arena Yokohama (pink characters)
• 5/3-4 Tokyo Big Sight South Exhibition Hall (green characters)
At these dates and locations, MyGO!!!!!×Ave Mujica joint live 「わかれ道の、その先へ」and Lawson Entertainment presents Card Game Festival 2025 were held respectively.
By conducting exploration at the two event venues, you can discover the following special problems.


By solving these and combining the newly obtained alphabets of Chihaya Aion and Kaname Rakuna with the alphabets of Nagasaki Soyo, Takamatsu Akari, and Shiina Riki obtained from the CRYCHIC course, we were able to obtain alphabets for all members of MyGO!!!!!.

When we apply it to the location of MyGO!!!!!on the poster as before...

The final answer was 「PROEM」.
It is a word referring to a prologue or preface in literary works or academic papers.

When the number of players who completed these 4 courses exceeded a certain number, the following image was posted from the official BanG Dream! X.
https://x.com/bang_dream_info/status/1918592745137922371
Achievement rate reached 100%! This completed the game...
Or so I thought.
When comparing the progress images that have been posted so far, the logo in the upper right is missing.
Thinking that there might be something, when we tapped on the image...


There was a Final Question hidden there!
This seems to be the truly final problem of this 「Ave Mujica Mystery Rally」.
Only numbers and symbols exist, and it's an extremely difficult problem, but if you can imagine from the second image that 「this seems to be the problem statement」,
you would come up with the idea of 「wanting to put some character in the circles」.
When it comes to characters that can fill such a large number of frames... they are what you players have accumulated.

That's right, the answers to the previous puzzles.
By the way, even without knowing the answers for the two MyGO!!!!!members mentioned above,
• There are only two six-character answers: 「かがみうつし」and one other
• There is only one three-character answer: 「こかげ」
• 「かがみうつし」and 「こかげ」can only be connected on the left side
• Due to the relationship of small characters, there is only one place where 「はっけん」and 「こうちゃ」can fit
By keeping these in mind, we can almost confirm the characters to fill in,
and by noticing that the 1, 2, 3 numbers on the left side of the second image are in the same font as Q4's 「むつみ」and the arrow is pointing in the reverse direction of Q5's 「go back one in the fifty sounds」rule, we were able to perfectly grasp the positions.
When we fill in all the answers and complete the sentence, it becomes like this.

The problem statement of Final Question is, 「The final answer is 'dream' in English」
The answer that concludes this mystery rally is, of course, also a five-letter English word.
The final answer was, 「DREAM」.

This is everything about the mystery rally themed 「BanG Dream! Ave Mujica」.
Thank you very much to all who participated!
