Asta:
About Ruan Mei  I liked the charm Miss Ruan Mei was wearing on her sleeve and asked where I could buy one like it — but I was surprised to learn that she had hand-embroidered it. And I was equally surprised when she gave me my own hand-embroidered charm the next time she came to the space station. Her craftsmanship, like her research papers, is superb.
Herta:
About Ruan Mei  Ruan Mei is a genius among geniuses — I won't deny that. I don't always get along with her, but I admire her...  Maybe the admiration is mutual.

Greetings  Want some pastry? The plums used in this recipe are freshly macerated, and I waited in line a long time for them.

About her origin  After catching the attention of Nous, I left my hometown and began my research on the origin of life in a secret corner of the universe — please don't ask where.

About Self: Name  In the grand fabric of life, both parents are equal, and thus my name takes the last name of each of my parents.

Chat: Genius Society  You don't have to listen hard to hear the gossip coming from the Genius Society — Mad Scientist. I'll take it as a compliment.

Hobbies — Pastry tasting  As someone with a sensitive palate, I only need one small bite to judge the taste of pastry. I favor seasonal ingredients such as fresh fruits, flowers, and herbs. Pristine slices of life preserved inside a pastry — these provide the best dopamine response food has to offer.

Hobbies — listening to opera  I've never been able to really get into modern music, but I find opera music enchanting. Time passes like a river whenever I listen to the strings and voices in an opera performance.

Annoyances — Talking  The redundancy of words and the restrictions of verbal communication sound like empty noise to me. It makes me sad...

Sharing — Embroidery Techniques  The feel of embroidery is similar to growing a culture in the laboratory — Fine control of the wrist, just the right angle, and total commitment.

Knowledge — The height of life  Without accelerating or postponing the arrival of death, life will always wither. Though we may be reduced to particles, we can reach new heights.

Knowledge — Rational Research  Humans overestimate the infallibility of logic, and in clinging to reason can become slaves to their emotions. Science is born from fanaticism — that's a gift.

About Herta  Some may find her personality unbearable — I can understand the sentiment, but I simply don't care. Of course, Herta knows this too, so I accepted her invitation.

About Screwllum  Screwllum and I have very different understandings of life, but I don't think he realizes it. Fortunately, our communication is limited to matters related to the Simulated Universe.

About Stephen  Put a watermelon parfait in Herta's office and Stephen is sure to show up. Remember, the pumpkin ones will never attract him — those are for warding him off.

First Meeting  I am Dr. Ratio, a scholar and teacher of the Intelligentsia Guild, and one of the Mediocres. If one day your brain shows symptoms of dullness, then please give the doctor a call.

Greetings  You look distressed. Is something troubling you? If so, you can figure it out yourself.

Parting  Another day has passed. If your problem still hasn't been solved, is it possible that the problem is you?

About Self — Headgear  First, with the headgear on, isolated from my five senses, I can think without interference. And second, I don't have to see stupid people. Of course, they don't want to see me either.

About Self — True appearance  I don't mind revealing my true colors if it helps me teach students and treat patients. But in my experience, it's usually counterproductive.

Chat — Intelligentsia Guild  The Intelligentsia Guild is often seen as a vendor of knowledge, but the right to set a price is always in the hands of the buyer. When someone is willing to listen to knowledge that is being disseminated and circulated, a price is created.

Chat: Genius Society  They dedicate themselves to truth... And it's right to say so — after all, everything they do is for the sake of Nous.

Hobbies  I can't stay away from books and bathtubs, especially the former. When one's head is stuffed with filth, one's body is no cleaner.

Annoyances  The most annoying thing about idiocy is that you can't explain it to an idiot.

Sharing  Before you ask a question, why don't you consider whether the answer has already been determined? It is better for everyone if such questions are not asked.

Interesting Things  The beauty of truth is that it never changes, even when no one understands it. Well, that's true for me, at least.
archive_ratio_12  About Herta  Herta is a quintessential genius — a natural wonder who sees no one as her equal. I have no doubt that she is talented, but I doubt whether her talent is always helpful to others.

About Screwllum  In his field, Screwllum is trying to establish new laws. I prefer to call such a person a monarch, rather than a genius.

About Ruan Mei  How many people have been fooled by her claim to fame as a hermetic genius? It seems to me that she wants to explore much more than just life. Just wait and see — the Genius Society member with all the real ambition is her.

Navia Q is about the same range as Ayato's. It follows you like Gorou's Q
It scans enemies, if you are far from them it will miss most shots. The explosion seems to be the sphere with center being on ground level.
This is not a bullet. Flying enemies will get hit only if they have a part of body inside that sphere.
There's an issue with scanning enemies that elevate themselves. During the Thunder Manifestation, most shots don't target them and go randomly.
Other flying enemies might or might not be hit, depending on their height.
For example, the Scara/Nilou boss: You can hit his tail with the explosion if it's flapping low.
Spectres might or might not get hit. Small Hilichurls inside Venti's Q face a similar situation, depending on the spin.

She comes to Penacony as a "Galaxy Ranger" and attends the family's banquet. Although she keeps her distance from the protagonist, she will help them when necessary. In the story, she reveals her true identity as an Emanator of Nihility: Nothingness.

On the surface: a cold and silent intergalactic ronin, an ascetic imperial maiden. She has embarked on a lonely journey for vengeance, but still seems to have goodness in her heart.
In reality, she is an IX Emanator of Abundance, a "Self-Annihilator" born out of nothingness, with no memory or past, wielding a sword that cuts off the path of life.

Firefly, formerly known as AR-26710, was born in an incubation pod of the Falakor Galaxy. As a genetically-modified baby, fate left her with only one future: To become the pilot of the Molten Knight "Samuel-IV" (referred to as Sam), and to join the endless war between humans and The Swarm.

But before Firefly set foot on the battlefield, her fleet was ambushed. The overwhelming argenites destroyed the ship, wiping out the army in space. Decades later, the drifting wreckage was recovered by the Stellaron Hunters. After waking up from a deep sleep, she was told that her old planet had perished in the catastrophe caused by the Antimatter Legion. But, the centuries-long war between humans and insects was finally proclaimed as over by a third party from outside.

So Firefly took the Molten Knight armor and joined the Stellaron Hunters. Her life was on a countdown, but Elio says that this journey will teach her how to live. Elio stopped there, the answers to her questions are for Firefly to find out herself. So before arriving at her predestined conclusion, despite only having a fleeting lifespan akin to that of an actual firefly, she is willing to experience anything and everything.

 Due to gene editing, Firefly's aging is different from that of ordinary people. One day, she will rapidly age and die. Compared to long-life species, she is a short-life species.

The Molten Knight is actually a weapon made by humans using argenite husk. Whoever pilots it will be affected by the Path of Propagation, and their body tissue and mental state will be corroded, resulting in mutations until death.

One of the leaders of The Family. After Hanunu (the first ruler of Penacony), died of illness, Sunday was invited by the Oak Family to help find a solution to the hypersomnia mutation crisis 

Sunday's proposed solution to the mutation was to use a Stellaron that had been kept under the stewardship of Hanunu. He proposed to activate the Stellaron in order to create a "wedge" in the Dreamscape — a creation of the Enigmata — thereby stabilizing the local area of the Dreamscape. This would enable Penaconians affected by hypersomnia to travel through the Dreamscape and seek refuge, thus allowing them to return to their normal sleep cycle in reality.
