Hello everyone,
This is Toru Nakamura, director of Vivid World.
Today, I’m excited to share a peek at a brand-new battle system we’ve been building behind the scenes:
💎Union Skill💎
This is one of the big additions we’re introducing as we push Vivid World beyond what we originally envisioned.
I hope you’ll like what we’re cooking up!
🍎 Union Skill: A Bond Between Allies Turns Into Power
Union Skills are powerful combo techniques that trigger when two specific units become partners.
This “partnership” unlocks under a certain condition, but we’re keeping the details under wraps just a bit longer🤫
(It’s nothing too complicated)
Once a partnership is formed, those two units will be able to unleash a unique Union Skill during battle⚡️
The screenshot below is still a work-in-progress, but the idea is simple:
If both partner units are on the field, a special skill becomes available.
And yes, we’re creating brand-new effects to give these moments the impact they deserve!

🍎 So… What’s a Partnership Exactly?
Partnership is a one-on-one bond formed between units under certain conditions.
Let’s say you upgrade Unit A for the first time during a run. At the same time, Unit B is randomly selected as their partner.
Once this bond is formed, it’s mutual and locked in for that run.
Even if you upgrade the unit again, their partner won’t change.
After all, it wouldn’t feel right if your *partner* changed on a whim 🌞🌝

🍎 What Triggers the Union Skill?
If two partner units are in your party and a certain condition is met during battle,
their Union Skill will activate. It only triggers once per battle.
The kind of skill will be set according to the combination of their color symbols,
adding another layer of strategic variety.
And when it goes off, there’s a little cut-in to mark the moment.
It feels quite satisfying when you pull it off💪
🍎 In Closing
Union Skills aren’t just flashy finishers.
They add a new layer of strategy built around team composition, tactical use, and timing.
We wanted to bring something that combines both gameplay depth
and a little drama of pairing two units together.
We’re still refining and polishing things, but I hope this gives you a taste of the
direction we’re heading.
Can’t wait for you to try them out!
Thank you so much for reading all the way to the end!
(And yes… I did say I’d post monthly. Sorry for the delay 🙇♂️)
For the next post, I’m planning to talk about one of the familiar faces from Vivid Knight🐭
We’ve added a few more interesting features to their role this time around,
and hopefully longtime players will enjoy what we’ve done.
See you in the next dev blog.
