Yukiiro Sign (ユキイロサイン) Review

That one Aonatsu Line everyone hyped to hell and back got a spiritual successor a little over a year later: Yukiiro Sign (ユキイロサイン).

Why “spiritual successor”? Same writer, same artist, different company — some outfit called wonder fool. I’m all for them ditching the shitshow that is GIGA, but wonder fool isn’t exactly a saint either. Look at the garbage they’ve put out. Feels like they’re just publishing leftovers nobody else wanted.

Anyway, I was still hyped, because Aonatsu Line was goated, so this had to be goated too. A bunch of otaku were dying to feel their youth again through this game (even though they never had one).

Then it came out and I played it, and I have to say, unfortunately: this game does not deliver what most people wanted.

The character setup copies Aonatsu Line almost exactly — still three heroines, one male sidekick. Difference is they apparently had money this time, since even random NPCs got sprites. Guess the budget really went up.

The story is set in Matsumae, Hokkaido, the “Little Kyoto of the North.” Our protagonist and his childhood friend Miku… sorry, “Nakura Miku” — wait, no, “Nakura Miku” is wrong, it’s “Nakura Miku”… whatever, it’s Miku — welcome two transfer students at school. One is Sve from Russia (full name way too long, forgot it), the other is Takagi Kyouko, a ski athlete from out of town who’s here rehabbing an injury while training. And so the three begin their winter story.

The common route is a thoroughly generic setup. The three arrive in this “Little Kyoto of the North” and immediately start scheming to do something — like pitching a tourism promo project for the town. Following the principle that the foreign monk always chants the best sutras, the Russian girl Sve proposes a “mini ice festival” and a café in the snow (no idea how that’s even supposed to work). This absurd idea somehow gets approved by government officials, they actually pull it off, and the common route ends.

Route selection is dead simple. At the New Year shrine visit, your bro asks who you’re into. Whoever you pick, that’s your route.

Takagi Kyouko Route

Kyouko’s route is probably the only one that looks remotely normal. Once you’re in, a girl named Yuda Yui shows up loudly and seems to hate Kyouko’s guts. Kyouko says they knew each other before, and she transferred here without telling Yui, which is why Yui’s pissed.

After some digging, it turns out Yui is a total tsundere. She admires Kyouko one-sidedly, took up skiing because Kyouko skis, all to get closer to her. But Kyouko ignores her, transferred without a word, and Yui’s annoyed — so she keeps showing up aggressively, picking fights on purpose, just to get Kyouko’s attention…

A true hero among female losers.

Eventually Kyouko understands Yui’s feelings and they make up. The protagonist swoops in and starts dating Kyouko.

After that I don’t even want to talk about it. It’s just sex, dating… and weirdly enough, they actually have a fight!

Holy shit, first time I’ve seen a couple fight in an eroge! So realistic. But the content of the fight is stupid as hell. Kyouko doesn’t really want to keep skiing, but the protagonist keeps repeating like a broken record that she needs to overcome herself and not be scared of hardship. He forgot the most important rule of fighting with a woman:

Women don’t fight to be reasoned with. They fight because they feel bad.

So reasoning with a woman during a fight is useless. You need to make her feel better. That’s why scumbags always get forgiven over and over — they never argue when they screw up. They hug, they kneel, they hit the woman’s emotional line directly, steer her away from “emotional pain,” and the fight fizzles out.

Anyway, Kyouko decides to keep skiing in the end, and she and the protagonist stay together as a couple. Story over.

As for Yuda Yui — a loser is a loser. She gets a hug, that’s it. No chance to get closer to Kyouko. Wonder if she can get close to some shark otaku in Osaka.

Nakura Miku Route

A profoundly stupid route. Early on, Miku’s older sister comes back from studying in the US, and the whole atmosphere turns awkward for everyone.

Why? After a bunch of melodrama, we learn that the protagonist once pursued Miku’s sister and got dumped.

And when Miku finds out her sister dumped him, she thinks he’s so pitiful — nobody wants him anyway — so she proposes they date. They go out for a while, the protagonist feels nothing between them, and it fizzles out.

Later, the protagonist and Miku rekindle things. Miku’s feelings get complicated — she can’t tell if she likes him or if it’s just possessiveness. She admits that when she saw him get dumped by her sister, she proposed dating because:

“My strong possessiveness kicked in. I felt everything should be mine, including my sister’s leftover boyfriend.”

Honestly, I’ve seen that kind of possessiveness in men. Women… well, if you say so.

Anyway, more couple fighting, bro fighting, they make up, couple lives happily ever after.

And the stupidest part is Miku’s sister, who’s a low-EQ moron. How did this idiot even study in the US? No idea.

Sve the Russian Girl Route

Also a very simple route (they’re all simple, apparently). Sve is Russian, an exchange student from Japan’s sister city, and she’s here with a purpose.

To find her biological mother.

Sve is half-Japanese, half-Russian. Her father is Russian, her mother Japanese. Both apparently worked in diplomacy, and because of their relationship, this Japanese city and its Russian counterpart became sister cities (what kind of logic is that).

After they married, the parents started fighting. In Sve’s memory, her father always bullied her mother, and eventually her mother fled back to Japan in a rage and never returned. Sve came here to trace her mother’s shadow from memory — eating what her mother loved, doing what her mother did. If she could find her, even better.

After a series of investigations and calls to the local government, the protagonist gets shocking news.

Turns out it was the mother who unilaterally abandoned Sve and returned to Japan. Sve’s father was actually good to her. The mother never really liked her half-Japanese daughter.

Sve’s search was one-sided longing. And it turns out her mother remarried after returning to Japan and has no interest in meeting her.

Sve takes the truth hard, thinks about it, looks at the ax in someone else’s hand, and forgives her. By then she and the protagonist are already together, after all.

The ending: Sve’s exchange ends and she returns to Russia. The protagonist plans to study abroad in Russia, and they decide to keep seeing each other.

Just don’t know if it’ll end up a mess like Sve’s parents.

If I had to rate this game directly, “mediocre” might be generous.

Remember what made Aonatsu Line good?

• Short, fast-paced
• Lots of negative space and cinematic storytelling
• Focused on youth — basketball, summer break, fireworks
• Natsuwa Koto on the cast (lol)

So what does this one have?

• Bloated, tedious plot — hours of agonizing over trivial shit
• No cinematic storytelling, just generic slice-of-life
• Not youthful at all. Nobody plays ice hockey, nobody wants to go shovel snow in winter. That ice festival café is pure nonsense. Oh right, and fireworks
• Not a single CV I’d fap to (lol). Oh, the Kagoshima drunk might count, but she’s not a main heroine (

Yukiiro Sign perfectly avoids everything that made its spiritual predecessor succeed. Or rather, Aonatsu Line’s success was an accident. Low budget meant lots of negative space, which turned into a cinematic effect. Low budget meant shorter plot, which made it feel tighter. Low budget meant fewer side details, so the emotional focus stayed on the main cast. Low budget meant the writer just ripped off the famous short film Fireworks, which gave it more atmosphere…

Man, thinking about it, the lack of budget was actually a good thing! When an eroge gets a budget, the writer loses his mind and starts padding. When there’s a budget but no Fireworks to copy, he thinks he’s a literary genius of youth?

Sure, Yukiiro Sign puts some effort into depicting women’s inner feelings — possessiveness, desire to be seen — stuff that exists in reality. But the writer’s skill isn’t enough to pull it off, so it comes out half-baked: bloated, pretentious, and laughably awkward.

Oh, have you seen those youth idol urban romance dramas? The ones starring Yang Mi? It’s exactly that vibe.

The writer also loves sprinkling “trivia” into dialogue to show off — like how the Russian character in Street Fighter was originally set as Soviet, or early Soviet socialism, random crap like that. Oh, and I still don’t know what the point of this “Russian exchange student who speaks Japanese better than locals” is. Why Russian? And I can’t find any Hokkaido city with a Russian sister-city relationship. I heard there are quite a few Russian descendants there, so a “research game” wasn’t possible either.

Overall, this game is a “half-baked neither-here-nor-there.” If they’d trimmed the plot, cut the fake Russian girl, replaced her with a Japanese character, and leaned into Japanese youth-literature tropes, it might’ve been salvageable. As it stands, it’s just an incredibly generic “degraded P.A. Works-style eroge” that’s also way too long.

While playing, I kept missing Aonatsu Line. I remember complaining about that scene where the school thug threatens the protagonist and his bro to a basketball showdown. Looking back, I was so naive. Compared to Yukiiro Sign’s endless plain water, I’d rather watch that basketball scene — and if there were a brainless fan next to me going “This is a classic youth-literature trope~” nonstop, even better.
