Sunday is a young man with fair skin and golden eyes with navy pupils. He has smooth, shoulder-length silver hair with a fringe swept up to the left, and wings of a similar color behind his ears. The left wing is pierced with two gold stud earrings, and he has a golden halo with details resembling eyes behind his head, which represents his Halovian heritage.
Before his playable outfit, Sunday's design consisted of a white sleeveless coat, a light gray unbuttoned blazer, a black turtleneck with a golden ornament in the middle resembling an eye, and a navy colored, wing-like vest under his blazer. He also wore white gloves with golden, cross-shaped cut outs, as well as light gray pants and black loafers with gray outsoles. On his left he wore a golden ornament attached to a blue cape and tassel, and his coat and blazer were open from the back, exposing his vest.
As a playable character, Sunday now wears a long-sleeved tailcoat, the sleeves stopping at just below the elbow. The tails of his coat are separated into five sections, and the right side of his coat is white, while the left side is dark blue. There are several golden ornaments on his coat, along with white straps that cross along his body. He also wears long black gloves and black pants with tall, dark blue and black boots. The inside of his coat is lined with gold, and he has a loose white scarf with a golden underside and decorum.
Sunday's personality is defined by his deeply ingrained fear of loss of control and a resulting need for rigid order, stemming from childhood trauma and a desire to create a pain-free paradise. He is outwardly calm, intelligent, and meticulously organized, but this conceals a deep-seated paranoia and a compassionate but flawed savior complex rooted in shame and the belief that the weak are destined to suffer. This leads to his obsessive rumination, perfectionism, and difficulty with genuine emotional expression.

"To my dearest sister:
I've eaten all the desserts you left for me! I can't help it — the pudding tarts were so delicious that I couldn't resist eating three of them before music class! Unfortunately, the loud witch teacher said my voice sounded like a snarl, and I sang like a duckling, so she sent me out for punishment. And guess what? I ended up eating a fourth tart outside the classroom!
Fortunately, I've been practicing the piano diligently, and Mr. Big Guy always praises my talent. Now, I can play a melody in its original form after hearing it just once — just as awesome as you! When you come back next time, we can play together as a duet on the same piano, and we can have another concert!
You don't need to worry about our little bird. It's been flying a bit higher each day. With the lovely weather we've been having lately, I'm sure it will be able to take flight soon! This afternoon, while I was tending to mom's grave, I spotted several birds looking like our bird. I know our little one will join them before long!
How time flies! I've recently begun taking Family lessons from the Bronze Melodia in the church. That means — I'm gonna become a super, super awesome person in the future! Then, we will surely transform the Dreamscape into a super, super good place in the future!
I've mailed some SoulGlad with innovative flavors together with this letter. Some of them are a bit unusual, but they're fun, and I really want you to give them a try. If you enjoy them, I'll be happy to send more!
(And if you come across any delicious pudding tarts, send some on my way too!)
Don't overwork yourself!
Support you always!
Your big brother"

"To my dearest sister:
I received the records you sent and played along with a few songs — they were wonderful. The record store on Penacony is now bustling with activity, and posters of your new album are adorning the streets everywhere. There are so many people complimenting you and asking if they can get your autograph.
It's probably for the best that you're not coming back right now. Penacony has changed. Dreamchasers are flocking in, and the economy is booming like never before. However, the Dreamscape has become much more chaotic than it used to be. I never would have imagined that the Bronze Melodia would face such significant challenges.
Entrepreneurs have imposed extremely unreasonable working hours to monopolize the industry, forcing workers in the Dreamscape to work twelve-hour shifts before they can take a break — only to receive meager paychecks in return. Speculative and high-risk industries are all over Penacony, where dreamchasers arrive with lofty aspirations, only to find themselves among the destitute...
Recently, a stowaway approached me for help, explaining that he had spent everything he had just to stay on Penacony, only to be discovered by the Bloodhound Family. He assured me that he would repay all his debts later, which is why I asked the Bloodhound Family to show him some leniency. However, every time I consider how many others like him there are on Penacony, I can't help but wonder if everyone has the opportunity to make the right choices.
If I've calculated correctly, you should be starting your next concert tour by the time this letter reaches you. You don't have to worry about Penacony. I know you are a kind person, but not everyone shares your heart. Always remember to take care of yourself.
There For You Always,
Sunday"

"To my dearest sister:
I have received the galactic specialties. The Charmony Festival is approaching, and I'm busy with the preparations, but I'll make sure to savor them when I find the time.
About the traitor in The Family... I've been informed. Your suspicions are correct. This matter is indeed linked to the deaths you observed, and it's even more connected to the mysterious Watchmaker. But since you have been away from Penacony for a long time and may not be familiar with the situation here, I would advise that you refrain from acting rashly.
Regarding your loss of voice, your top priority should be to recuperate. If you are genuinely unwell, I will consult the Dreammaster about the Charmony Festival to see if we can have a special arrangement. You believe the loss of voice stems from the impure nature of Penacony's Harmony, and I concur. Unfortunately, the only thing that seems truly pure in Penacony is perhaps human "greed."

Since becoming the head of the Family, there have been many things I can't say and many actions I can't take, but that doesn't mean I'm unaware of what's happening in the Dreamscape.
While we may both be walking on new paths, I can assure you that I have never failed to uphold the promises I've made.
Head of the Oak Family, Sunday

"To my dearest sister:
It's been quite a while since I wrote a letter.
I may not be able to contact you for a while from now on, but I assure you, this will not be the last letter you receive from me.
A path full of hope can often be a path of full temptation, and thanks to all of you, I haven't strayed too far. In my current position, there's little I can do to make amends except to eliminate the lingering echoes of Order that remain on Penacony. By doing this, I can ensure that there are no more hidden dangers of Order in the Dreamscape.
To catch a glimpse of the sky, even a bird with a broken wing will choose to take flight again. Just like the little bird we raised together as children, it soared into the heavens despite knowing it might fall — because that was its destiny. I will never forget our shared wish to "make everyone happy," but now I must embark on a journey to seek fulfillment in the wider world. This is my destiny and my choice.
Mr. Yang has granted me permission to board the Express and travel as a passenger in search of my promised land. They are kind and of noble character. You should know them better than I do.
Many times, even when you don't say it, I still see you as a child who needs protection. But you've long since grown up, and I'm truly relieved that Penacony has you.
I have tended to Mom's grave and picked a blue flower to carry with me. She will continue to bless us as always.
Finally, thank you for the giantmoa pudding tarts. They still carry that same nostalgic taste after all these years.
On the road,
Your big brother"
