RTai-yi’s awakened ability turned out to be Universal Translation.
Tai-yi can understand the speech of all living creatures, and whatever Tai-yi says can be understood by all living creatures in return.
It seems that what grows through training is probably the range. After discovering that she had awakened to a translation ability, she spent time testing what kinds of creatures she could target, how long the translation would last, and whether her power translated actual voices or transmitted thoughts. While she was doing that, her base stats stopped growing. In the end, she capped out after eight growth cycles, with an effective range of three meters.

The ability seems truly universal. Her “Begone!” even worked on an ant, so it’s fair to say it works on all living beings. Of course, it doesn’t mean everything can be conveyed—if the creature can’t understand a concept, the words won’t reach it. For example, if she tells an ant, “Gather in groups of three,” it won’t understand “three,” so it’s impossible.
Commands like “Follow me” or “Help me” generally don’t work either. Understanding language and obeying commands are entirely different matters. Even humans, if suddenly told by a frog to “Spin around three times and bark,” might not comply—it depends on the person. Some would run away in fear, while others might just do it for fun.

When we used the Petrification PSI Drive to sedate Tai-yi and conducted experiments with her extracted blood, it created a “universal translation field” with a radius of 300 meters. Within that field, cats could communicate with all living creatures.
Yes—cats. Tai-yi’s ability translates between “cat language” and every other creature’s language.
Even inside the field, humans and dogs still can’t talk to each other. I tried injecting myself with Tai-yi’s refined blood serum; it let me understand cats, but I couldn’t understand dogs or mice at all.

So, it’s a very limited kind of universal translation. Being able to talk with all living creatures is an incredible advantage, but it has no versatility.
Tai-yi herself couldn’t expand it at all through training. If she could do human (Japanese) ↔ human (Chinese), or human ↔ crow, it would open up tremendous applications, but no matter how we tried, she couldn’t grasp it. No growth, no change.
Considering that Ig’s healing ability also couldn’t be adapted or expanded, it might be that powers transplanted into nonhuman creatures only allow base growth, not creative application. Perhaps it’s better to say they have broad utility from the start but zero expandability.

According to Baba, Tai-yi intends to use her ability to build cooperative relations with the underground cat and crow societies.

The coastal economic zone of Qitaohe City, facing Russia and Japan, is a bustling port city where fishing is also thriving. Stray cats have made homes around the fish markets and warehouses, clashing with housecats.
The strays look down on the domesticated cats as “collared ones,” too human-like for their taste, while the housecats see the strays as pitiful creatures who can’t survive without constant struggle.
To fight against the World Shadow, Tai-yi was planning to form a grand alliance that transcended the boundaries between housecats and strays.

Stray cats, compared to the exercise-starved housecats, are quick, sharp, and tough fighters. They live off fish market scraps and hunt warehouse rats, so they’re well-fed. Though they number only a tenth of the housecats, they’re a warrior class. If they joined forces with the well-fed, safe, and veterinarian-supported housecats, the World Shadow wouldn’t stand a chance.

She’s even considering drawing in the crow faction, long at odds with cats over food and garbage dumps. Lately, Tai-yi has been busy with diplomatic outings to forge this alliance.
She’s a charismatic black cat who used to be the boss of the neighborhood housecats. I don’t really get cat society, but an alliance centered on her doesn’t sound impossible. Honestly, I’d love to see a horde of cats and crows launching an all-out attack on the World Shadow. That’d be way too cool.
If the cat alliance succeeds, Tai-yi will truly be the Tsukiyomi Chinese branch chief. Baba’s foresight is insane. Centuries of being a queen weren’t for nothing.

Meanwhile, Haoran who has gotten used to Tai-yi suddenly talking and has accepted it, deepening their bond while continuing his basic training. His growth rate multiplier is 1.15x; he’s grown eight cycles now, with a gravity factor of 3.06×. How far his base stats can grow will likely determine how his ability is evaluated.
The record for most psychic growth cycles, excluding me, belongs to Oyabun and his 90 cycles. If Haoran reaches that, his gravity factor would be 290,000x. Just activating his power above an enemy would pulverize anything into mince. At that level, gravity 290,000x is 10,000 times that of the sun. Fusion would ignite, and maybe even a black hole would form. One careless move, and he’d wipe out the planet…

If it caps at an average of around twenty growth cycles, that’d be about 15–20x gravity—enough to turn bodyweight-based attacks into lethal strikes. If he learns to project it onto others, it’d basically be a one-hit win. Most psychics have some sort of “finishing move”: Shouta’s absolute freeze, Shige-jii’s spatial attack, Medu-chan’s petrifying gaze. As for me, my “finishing move” is more like cosmic destruction, so I don’t count. I’m just too damn overpowered.

Anyway, that’s all theoretical. It all depends on his aptitude. Once his growth stops, or once he hits around 10x gravity, we’ll start application training.
Application training focuses on “developing the sense.” Experiencing high and low gravity firsthand is key to mastering gravity manipulation. I’ve been discussing plans with Baba: getting him a spacesuit and telekinetically sending him to the Moon or Mars; buying a ticket for a zero-gravity space tour; or having him stay submerged in a pool to blur his sense of buoyancy and gravity. We’ll decide soon.

Now then.
Once Tai-yi and Haoran grow a bit more, we’ll officially bring them into Tsukuyomi. As for me, I’ve been pretty idle. I don’t understand Chinese, so my options are limited, and since I’m technically the boss of Amaterasu and “no longer with” Tsukuyomi, I can’t take center stage in their events.
Lately, Baba’s been giving me pocket money, telling me to go play around. My days consist of wandering around and hearing her progress reports in the evening.

Today it’s pouring rain, and I’m strolling through the warehouse district by the harbor. I lost my umbrella to a pickpocket at dinner. My barrier is always active so I don’t get wet, but it’s still unpleasant.
Night’s fallen; the area’s dark. Large warehouses line up neatly, with cardboard boxes, rotting crates, and rusted containers stacked in disarray.

There are many strays around here. I’ve injected myself with Tai-yi’s serum and am listening in on the cats’ conversations, testing the range and duration of the serum’s effect.
The strays are cautious and tend to flee if approached, but I’ve picked up bits of rumor that a black cat—likely Tai-yi—has been cozying up to the local strays.

After some walking, I realized it’d be smarter to wait than approach. Cats are sensitive to sound; they’ll clam up or run the moment they hear human footsteps. Hiding along their patrol routes, holding my breath, and listening quietly is the most efficient way to gather info.
If only I could use telepathy to eavesdrop, but her translation ability and my telekinetic listening don’t synchronize.

I slip into a large cardboard box lying between two warehouses, crouch down, and curl up. I’m just a roadside rock. A harmless decoration. Please, dear cats, pass by without minding me.

I wait motionless for about an hour, but not a single cat shows up. Then it hits me—cats probably don’t take walks in heavy rain.
I’d always imagined wild animals just going about in the rain, but cats hate getting wet. The ones who enjoy rain are frogs and snails. Not cats.
Am I actually a bigger idiot than I think…?

Just as I sigh and start to stand, a tabby cat passing by locks eyes with me. It has a deep scar over its right eye—one-eyed.
Its whole body’s soaked, shoulders hunched, walking wearily.
It stops in front of me and speaks, a bit confused.

“Meow, meow meow (Say, what are you doing there)?”

The compressed voice echoing in my mind sounds like that of a young man. Looking closely, I can see scratch marks and bite wounds all over him, with a bit of blood seeping out. Looks painful. Must’ve been a fight.

“Meow? Mrew… meow mew mew (Are you all alone? Me too… all on my own).”

I hesitate, unsure how to explain my situation, and the tabby continues speaking on its own.
His words are heavy with melancholy. Did something happen to him…?
That single blue eye looks so lonely it hurts to meet his gaze. Should I say something? I can talk to cats right now, but would speaking startle him?
As I waver, staring at him, the tabby gives a wry (probably) smile and turns away.

“…mrreew? Mew meow ( …Why don’t you come along? I have warm food for us).”

He starts walking, glancing back over his shoulder. I step out of the box and follow his striped tail.
I don’t really know what’s going on, but somehow, sitting in a cardboard box in the rain, I got picked up by a cat.
Things are about to get interesting, nya! I’m gonna follow this kitty, nya!
