Stories
6Story 1
The wise and experienced former Anti-Entropy Sovereign who inherited the name of the world — Welt. He has saved Earth from annihilation time and time again.
After the incident with St. Fountain came to a close, Welt had no choice but to venture with the initiator of the incident to the other side of the portal.
Perhaps even he did not expect the new journey nor companions that awaited him there.
Story 2
On the way to the portal, Welt took out a pen and started outlining a sketch. For the eight years prior to that moment, he'd been repeating this job.
Going back further in time, he would construct objects in a different way, as long as the images could be pictured in his mind. But he could never regard that as "creation," because they were just the way the original is. Those had nothing to do with his mind.
This is just the duty of the man who inherited the name of the world. If the world needs him to save it, then he will become that hero without hesitation. He has fallen down many times and been mocked even more, but he will always stand before everyone either in the past or the future — he will never change.
Only now, he finds himself embarking on a new journey.
Story 3
When Welt returned to that dangerous cosmic battlefield, he could feel his blood start to boil once more.
Even when his spaceship lost power and was drifting aimlessly through space, he joked casually with his companion: "The end of one adventure is often the beginning of another."
When a passing-by Himeko managed to save them and informed them that they couldn't go back home, he kept up his jokes: "This is like something out of a cartoon, and it's far too coincidental to be real."
Life really is this coincidental.
Since he can't find his way back home and can't live out a peaceful existence for the time being, why doesn't he take up arms again and fight?
This time, there is no burden or destiny to bear. Everything shall obey his own will.
Story 4
These days, Welt rarely fights, and it remains unknown whether or not he retains the strength from his heyday. Gravity manipulation has remained his usual combat means, ever since his cane was transformed from the Star of Eden.
He suppresses his enemies with gravity, even creating a kind of mini-black hole — what he considered his everyday powers are met with amazement by the youngsters on the Express.
"Mr. Yang's incredible, amazing!"
"If you need help with anything, Trailblazer, go ask Mr. Yang."
"You need to take turns. Let him rest a little while..."
He is shocked to realize that his carelessness and surety are the results of his countless experiences, marks of the relentless passage of time he had endured. However, the youths aboard the Express are like blank pieces of paper, writing out their own lives.
What kind of responsibilities should he take on in their lives?
He couldn't help but think of the names of people throughout his life who had helped him before.
Story 5
— Welt's Log ██/██/████.
███'s relationship with the protagonists:
█—███'s sparkling personality is just like the protagonist in a cartoon. Go for it!
███ — A lively youth. I hope she can keep being imaginative, and not feel guilty even if she stumbles. Youths are always going to make mistakes, and ███ will be able to support her.
██ — A reliable youth. There's no need to worry about him. I hope he can chat more with ███, but if he doesn't want to, then that's fine.
██ — I can trust this companion with my life, ███ believes she will make the right decision.
██ — A common character in cartoons. Seemingly just a normal creature, but actually possesses frighteningly powerful abilities and a complicated background.
Note: If I ever get back home, consider making a cartoon out of this.
Voice lines
First Meeting: Hi, I'm Welt Yang. If there's something you need help with, you can come find me anytime.
Greeting: Hm? Still half asleep? Don't force yourself. You should get some more rest.
Parting: Can't sleep? I understand — inspiration always comes knocking in the small hours. It's hard to ignore, right?
About Self: Previous Profession: I was an animator for eight years — my life was pretty routine. I guess it was a little dull compared with adventuring, but work is a very worthwhile thing. It brings dreams to life.
About Self: Reason for Boarding the Express: *sigh* It's a long story, and it involves a lot of people and incidents that everyone would like to forget about, haha. Best not to talk about it. In essence, I got lost in the universe, but was fortunate enough to come across Himeko driving the Express.
Chat: Arahato: Oh, there's a lot to say there. They only aired that series on my home world — I don't know if there's anywhere else in the universe that'd have it... I can use my mimicry power to show you a few episodes, but I can't guarantee the resolution.
Hobbies: Researching history and producing animations... I'd say they go hand in hand.
Annoyances: Y'know Trailblazer, you remind me of the main character in a cartoon or something — you seem to attract companions out of thin air... *sigh* I hope you don't mind me saying that. It's just... it seems like my own chances of going on an adventure have plummeted again...
Something to Share: My home was corroded by a force known as Honkai, but that hasn't stopped it from being a warm and beautiful world.
Knowledge: Do you know how the followers of Qlipoth the Preservation became the Interastral Peace Corporation? The Aeon wanted to build a wall, and humanity started searching for building materials so they could follow in Qlipoth's footsteps... it's pretty funny when you think about it.
About March 7th: March is curious about everything, and she's always getting me to do combat poses. She thinks I pull them off pretty well, apparently. You think so too? Hmm...
About Dan Heng: He's safe. I know he has his doubts... but he's one of the crew now. Himeko and I won't let anyone harm him.
About Himeko: Himeko's the kind of person that... gives off her own light. Even though we're traveling across the train's old route, you can see Himeko's dreams flashing before her eyes when you look at her. It's almost as if she's been on the train from the very beginning — always moving starward.
About Pom-Pom: Pom-Pom's always there to lend a helping hand, but I'd refrain from teasing them if I were you. The last person that did that...
About Dan Heng 2: There is a quote I like very much that I would like to share with him: "The galaxy is vast beyond compare, containing an infinite number of possibilities. An individual's fate shouldn't be limited to a single path ordained by heaven."
About Sunday: Having an ideal and pursuing it is not rare, but being able to start anew after that ideal is shattered — this kind of willpower will carry him far.
About Fugue: In the face of the seemingly unstoppable tide of destiny, we always have the freedom to resist... She must have fought an extremely tragic but heroic battle against herself.
About The Herta: The world is full of extraordinary complexity. Normally, researchers are only able to glean truth after dissecting the universe into categories... yet she revealed the essence of all things in such a miraculous way. If I hadn't seen it with my own eyes, I would never have believed it.
About Dan Heng 3: Growth might look like just taking one step forward, but it can only be completed after finishing a long journey. I am relieved to see how much more determined the light in his eyes has become.
About March 7th 2: Since experiencing this trip — or perhaps much earlier — March has become a mature Nameless. We needn't treat her like a helpless child anymore.
About Himeko • Nova: I always knew Himeko was full of surprises, but the beauty of the "Starblazer" far exceeded my expectations. Still, I must clarify: The charm of a giant robot isn't just about its looks. Without a doubt, it's her dream that gives it that final, brilliant finishing touch.
Eidolon Activation: New adventures, new friends... Great, isn't it?
Character Ascension: The passion of yesteryear isn't all that returned...
Max Level Reached: In the immense sea of stars, we too will leave our mark.
Trace Activation: After spending so much time with everyone, I feel like I'm starting to age backwards.
Added to Team With Trailblazer: As the protagonist of your own story, it's up to you to overcome and forge ahead.
Added to Team With Himeko: I don't often get the chance to fight alongside you, Himeko. It's time to show everyone what we can do.
Added to Team With Dan Heng: Having you here gives me peace of mind, Dan Heng. Still, best not to push yourself too hard.
Added to Team With Dan Heng • Imbibitor Lunae: Having you here gives me peace of mind, Dan Heng. Still... I'll stop nagging.
Added to Team With March 7th: Youthful energy is a good thing... but I'd appreciate a heads-up before you make any moves, March.
Added to Team With Sunday: There are both dangers and opportunities during interstellar travel... This is what companions are for.
Added to Team With Evernight: Seems like you have quite a few ideas about this fight.
Added to Team With Dan Heng • Permansor Terrae: No need to hesitate. I believe this is far from the limit of your power.
Added to Team With Himeko • Nova: Opportunities like this don't come around often. I'd better make sure I keep up with the younger generation.
Battle Begins: Weakness Break: Seems you need to experience some hardship.
Battle Begins: Danger Alert: Stay calm.
Turn Begins 1: Leave the rest to me.
Turn Begins 2: You can still walk away.
Turn Idling: Let's finish this.
Basic ATK: Stand down.
Skill 1: Calm your body and mind.
Skill 2: I won't go easy on you!
Hit by Light Attack: I'm fine.
Hit by Heavy Attack: That won't stop me...
Assist Skill: Trailblaze Companions: Go forth to connect more worlds.
Ultimate: Activate: You know nothing of the weight behind this power.
Ultimate: Unleash: Witness the stars shatter before you... Survive or be destroyed, there is no other choice.
Finishing Blow: Trailblaze Companions: Become the stars, and light up the cosmic night!
Downed: I'll leave the rest... to you...
Return to Battle: I can't relax just yet.
Health Recovery: Timely treatment.
Technique: Stay.
Battle Won: The galaxy is vast beyond compare.
Treasure Opening 1: Interesting.
Successful Puzzle-Solving 1: Well figured out.
Enemy Target Found: ...No harm in trying.
Returning to Town: The next destination...? Up to you.
Treasure Opening 2: This will definitely come in handy.
Precious Treasure Opening: You don't see these every day...
Successful Puzzle-Solving 2: Now, that's talent.
