Bureau of Anomaly Control Fun Fact #1: A Lacrimosa will regularly spawn on the break room couch. Other common Lacrimosa spawn points include sun-warmed rooftops, quiet and rarely-visited stairwells, or the inside of a creepy-looking coffin that actually has soft, fluffy padding inside… There are 24 hours in a day, so sleeping for only 20 hours isn't that much, right? As ETD-4's adorable little ace, Lacrimosa may not be good at socializing, but her popularity remains sky-high. While her complaint letters are directly proportional to her property damage rate, the thank-you letters and fan mail she receives are equally staggering. Team relationships? Harmonious. Even when having lunch at Clicky Fast Food, when all the ketchup gets hogged and everyone has to dip their french fries in ice cream instead… it's no big deal. Perhaps because she's too innocent and pure, Lacrimosa has a unique "eye for discovering beauty." This manifests as: accidentally bumping into street signs hard enough to hurt her forehead, or taking exhausting routes that take forever to walk despite being quickly reachable by car. In these moments, Lacrimosa reaches the conclusion: Street signs, cars, powerful! Lacrimosa, must learn! "Actually, controlling Esper Abilities and creating all sorts of complex shapes out of thin air is actually much harder than people imagine. Lacrimosa has put in a lot of effort where no one can see!" —assessment from ETD reserve training staff currently in casts. What, Lacrimosa's missing again? Did she get lost? Where did she fall asleep this time? Or was she distracted by a roadside tomato jelly vending machine? Well, no worries. Trust that she's still a reliable ETD team member. When the team really needs Lacrimosa, she'll definitely come running. …Though it'll probably be at the cost of glass doors shattered all along the way.

Perhaps it's the price of her Esper Abilities, but aside from tomato products, Lacrimosa can't taste anything she eats. No matter how delicious food smells, eating it is like chewing soft, chewy, or crispy plain cardboard. The upside is that even when Mint has a "brilliant idea" and creates something like banana coco pumpkin pie, so long as it doesn't smell too questionable, Lacrimosa can eat it all with a straight face! Rumor has it that the tomato product brand "Tomato 100" once approached Lacrimosa, hoping to invite her to become their spokesperson. However, the collaboration was temporarily suspended due to negative social impact caused by the "Tomato Devil" Anomaly. Recently though, the brand seems interested in restarting the partnership… but we'll leave that story for another time.

Hethereau is just too big, and walking is just too exhausting. One day, Lacrimosa thought to herself: "It'd be great if I didn't have to walk." The next second, she found herself transformed into a little bat, flying through the air. Mm, much easier. Problem solved! However, now Lacrimosa had new troubles. After all, not every building had glass doors, but glass windows were everywhere. Ever since she learned to fly, situations where Lacrimosa's forehead and glass both get damaged have become increasingly common. To add to her woes, flying takes less effort than walking, so naturally closing her eyes and dozing off is pretty normal, right? If she actually falls asleep, however, she'll forget to flap her wings… and down comes a falling Lacrimosa from the sky.

As a devoted fan of the most famous cult manga "Duke K" in recent years, Lacrimosa naturally hangs out on Bagel, constantly keeping up with the latest news. Typing is too hard, so Lacrimosa usually just lurks without commenting. She's even too lazy to come up with a username, so she goes online using her real name. Unexpectedly, she was caught by a fellow "Duke K" fanatic called "GeneSectParanormalDeptAce" because of her frequent likes, and somewhat reluctantly gained a friend with shared interests. Her teammates are quite relieved that Lacrimosa has finally made a friend, but she still can't remember the other person's full username and usually just calls them "Net Friend With A Long Name." On the other hand, the other person apparently still thinks her habit of referring to herself in-person by her online username is rather self-centered…

The Bureau of Anomaly Control's employee files contain a photo of Lacrimosa from before she joined the team: sitting on the ruins of a completely flattened convenience store, concentrating intently on drinking tomato jelly. The files also show that her almost complete inability to control her Esper Abilities improved significantly after she spent some time training with the ETD reserve team. A pair of rings of unknown origin with obvious signs of use, received from a future captain, seemed to provide great help with her practice. Perhaps after she grows up, she'll be able to sense the true secret contained within those rings… but that's all in the future.

Just like most people can't remember their earliest days as an infant, Lacrimosa can't recall anything from before she became "Lacrimosa." Based on a line of text carved on the coffin where she woke up, Lacrimosa decided on her own name. Why don't other people get to decide their own? Don't adults always tell her that she should choose the kind of person she wants to become? However, names she didn't choose like "Mosa" or "Lacrimosa Senpai" also seem to be calling her. If she had chosen a different name, would she have become a different person? …Lacrimosa can't answer such complex questions yet. She only knows that her teammates taught her to respond seriously when her name is called. Lacrimosa has kept those words close to her heart. "That super-strong pretty girl from ETD may always have a blank expression, but she's surprisingly down-to-earth! When I greeted her on the street last time, she even responded! Oh my gosh, so cute!" Thus, her popularity among citizens rose a bit more.
