Studio KAI The Ramparts of Ice Season 2 Staff Changes: Full Breakdown and Studio Financial Analysis
There are some anime sequels where I look at the staff list and immediately start worrying. Then there are sequels like The Ramparts of Ice Season 2, where the more I look at the production credits, the more I find myself cautiously optimistic.
The first season of The Ramparts of Ice (Koori no Jouheki) worked for me because it never felt like it was desperately trying to be a typical high school romance. Its biggest strength was how uncomfortable, awkward, and genuinely human its characters could be. Koyuki Hikawa wasn’t simply the cold girl waiting for someone to “fix” her. Minato, Miki, and Yota all brought their own baggage into the friendship, and the series understood that emotional walls don’t disappear because the plot needs a romantic moment.
That is exactly why the staff situation for Season 2 caught my attention.
Studio KAI is coming into the second season after a difficult year financially, yet the production team isn’t simply shrinking. Several supporting positions have been added or expanded, while the people most closely associated with the first season’s identity are still in place. For a fan, that’s a much more interesting story than simply counting how many new names appear in the credits.
The Most Important News: The Core Team Is Still Here
Before getting excited about new staff members, I always want to know one thing: who is actually staying?
Thankfully, the answer is encouraging. The main creative structure behind Season 1 remains largely intact, which matters enormously for a character-focused series like this.
- Mankyū returns as director, continuing to guide the overall tone and presentation.
- Yasuhiro Nakanishi remains responsible for series composition and scripting.
- Miki Ogino continues as the primary character designer.
- Kanade Sakuma and Natsumi Tabuchi return for the musical side of the production.
That combination is probably the biggest reason I am not particularly nervous about Season 2. A change in animation staff can be perfectly manageable, but losing the people who understand the emotional rhythm of a show can be much harder to hide.
The Ramparts of Ice lives or dies on small moments. A glance that lasts half a second too long. A character choosing not to answer a question. A smile that looks forced before disappearing. These aren’t scenes where spectacular sakuga automatically saves the day. Direction and character acting matter more.
So, What Actually Changed?
The interesting thing about Season 2 isn’t a dramatic replacement of the creative leadership. It’s the addition of people underneath that leadership.
| Production Role | Season 2 Development | Why It Matters |
|---|---|---|
| Assistant Director | Hikaru Ishii added | Provides additional support for the director and production workflow |
| Sub-Character Design | Eriko Ito added | Allows supporting characters to receive dedicated design attention |
| Prop Design | Yuki Hamada | Adds more specialization to everyday visual details |
| Costume Design | Kotono and Yuuna Fueki | Gives character clothing and styling dedicated oversight |
On paper, these might look like relatively minor production changes. Personally, I don’t think they should be dismissed that easily.
Hikaru Ishii Could Be the Most Important Addition
The addition that interests me the most is Hikaru Ishii as assistant director.
An assistant director isn’t there to replace Mankyū or reinvent the series. The role can provide another layer of organization between the main director and the enormous number of moving parts involved in an anime production. Storyboards, episode coordination, animation departments, scheduling and day-to-day creative decisions can consume an incredible amount of time.
That gives Mankyū something extremely valuable: more room to concentrate on the bigger picture.
And honestly, that’s exactly what I want from Season 2.
I don’t need The Ramparts of Ice to suddenly become an animation showcase every five minutes. I’d rather have consistently strong character acting, good framing and carefully directed emotional scenes than a handful of spectacular sequences surrounded by rushed episodes.
Eriko Ito and the Smaller Details
Eriko Ito joining as sub-character designer is another change that makes sense as the story expands.
As the cast grows, the workload involved in maintaining consistent character designs grows with it. Supporting characters still need to look like they belong to the same world, particularly in an anime where ordinary classmates and family members aren’t just background decoration.
Then there are the dedicated prop and costume design roles.
These aren’t the kinds of credits that usually get fans screaming on social media, but they can have a surprisingly noticeable effect on a slice-of-life production. Clothes, school supplies, phones, bags, rooms and everyday objects help establish who these characters are without the script having to explain everything.
For a story this grounded in ordinary teenage life, those details matter.
The Financial Problem Is Still Worth Discussing
This is where things get more complicated.
Studio KAI’s reported financial difficulties in 2026 understandably caused concern among anime fans. Reports indicated a final net loss of approximately 565 million yen for the preceding fiscal year, leading to discussion about the studio’s financial stability and what that could mean for its productions.
It’s easy to look at a number like that and immediately assume the worst for every upcoming anime. I don’t think that’s a useful way to read the situation, though.
The studio operates within the broader ADK Emotions corporate structure, meaning Studio KAI isn’t simply an isolated company with no support around it. More importantly for this particular anime, the production staffing for Season 2 doesn’t look like a project being stripped down to the bare minimum.
In fact, the opposite appears to be happening in several departments.
That doesn’t guarantee a flawless production. Anime schedules are complicated, and having more names in the credits doesn’t automatically mean every episode will look incredible. But the staffing structure certainly gives me more reason to be curious than alarmed.
Season 2’s Music Is Changing, Too
Another change I’m genuinely looking forward to is the musical direction.
Season 1 had memorable theme songs, including Toumei by Novelbright and Sakasama by Polkadot Stingray. For Season 2, the production is moving into a different musical chapter with THE BEAT GARDEN performing the new opening theme and Superfly handling the ending theme.
That’s a pretty interesting combination.
The opening and ending aren’t just marketing material for me. When they’re chosen well, they can reinforce the emotional identity of an entire season. And with the relationships between Koyuki, Minato, Miki and Yota continuing to evolve, a fresh musical tone feels appropriate.
What I’m Actually Watching for in Season 2
I’m less interested in whether Season 2 can technically “out-animate” Season 1 than I am in whether it can preserve what made the first season emotionally effective.
These are the things I’ll personally be watching most closely:
- Character acting: Do Koyuki and the others still communicate through subtle expressions and body language?
- Pacing: Does the adaptation give emotional scenes enough breathing room instead of rushing from plot point to plot point?
- Visual consistency: Do the additional designers help maintain quality as the cast and locations expand?
- Direction: Can Mankyū continue balancing awkward comedy with heavier emotional material?
- Relationships: Does the romance develop naturally, or does the story start forcing drama simply because it’s a second season?
That last point is probably my biggest concern.
Once a romance anime becomes popular, there is always a temptation to turn every interaction into a major emotional event. The Ramparts of Ice was strongest when it allowed its characters to simply exist together. I hope Season 2 remembers that.
Why I’m More Optimistic Than Worried
Looking at all of this together, I don’t see a production team desperately trying to reinvent The Ramparts of Ice. I see a team attempting to expand the production structure while keeping its central creative voices intact.
That distinction is important.
Mankyū is still directing. Nakanishi is still handling series composition. Ogino remains tied to the character designs. Around them, Studio KAI is adding specialized staff who can take some of the workload away from the central team.
Could Season 2 still have uneven episodes? Absolutely. Could the schedule become difficult? Of course. No staff list can guarantee otherwise.
But as someone who genuinely enjoyed the first season, I would much rather see this kind of expansion than a wholesale change in the creative leadership.
The October 1 Premiere Is Getting Closer
The Ramparts of Ice Season 2 is scheduled to premiere on October 1, 2026, on Netflix, and at this point I’m mostly curious to see whether these production decisions translate into what matters once the episode actually starts playing.
Credits can tell us who is working on an anime. They can’t tell us whether a particular scene will make us pause for a second because a character’s expression feels painfully real.
That’s the real test.
For me, the appeal of The Ramparts of Ice was never about having the biggest fights, the wildest animation or the most complicated plot. It was about four young people slowly figuring out how to trust each other while carrying things they don’t always know how to talk about.
If Season 2 keeps that emotional honesty while using its expanded production team to maintain visual consistency, I’m more than happy to give it my attention.
October 1 can’t come soon enough.
