+ S1: Strong manually triggered burst heal
+ Great source of Status Resistance for allies, as it is not tied to a Skill or have other restriction
= S2: has a very high healing amount during its duration, but the RNG can make it unreliable if many Operators are in range

- Her Status Resistance buff has a rather short duration, so it can drop off easily, especially at lower promotion levels.
- Currently impossible to raise her Potential because she cannot be summoned normally.

Operator Overview
People are quick to dismiss Purestream as too young and naïve to know what she’s talking about, but those people do her a disservice. When her hometown’s water supply was polluted, only Purestream’s tireless research and hard work was able to save her people, and it has given her a perspective and a determination that cannot be stopped. Because Rhodes Island helped implement her purification strategy, she now works for them as a 4* Wide-Range Medic, using AoE healing and Status Resistance to keep her allies as clean and healthy as… well, as a “pure stream” of water.
A special note: Purestream was initially only available through a special “Purestream Pack” in the Store, as part of a charity collaboration. In CN, she was eventually added to Recruitment; this has not yet happened in Global but is likely to be the case in the future.
Purestream’s E1 Talent is Rapid Restoration, which adds a short-duration Status Resistance buff (halves duration of Stun, Chill, and Freeze) to her heals. This is particularly nice because, as a Wide-Range Medic, Purestream’s heals are less effective on allies on the edge of her range. The Resist buff adds a bit of utility to all of her heals, even the weakened ones, and Purestream can apply this buff to multiple targets using her Skills. Skill 1 is Healing Waves, which immediately grants a large heal to all allies in Purestream’s range, and Skill 2 is Lifespring, which causes Purestream to heal random targets within her range at decreased power but with greatly increased speed. Healing Waves is usually the better choice for consistent healing, but Lifespring can proc the Status Resistance buff more often throughout its duration, causing ailments to slide right off your team like water off a porpoise’s back.
Purestream’s stats are fairly unimpressive, leading to weaker healing output on top of the reduced healing to distant targets from her Trait, and being a Wide-Range Medic comes with a higher DP cost than most Medics. In situations where her Status Resistance buff is not needed, she can be a less-than-ideal choice for a primary Medic. However, she’s always an excellent back-up Medic due to her huge healing range and the strong effects of her Skills, and she shines like sun glitter on the ocean when she can leverage her Status Resistance buff to protect her friends. Protect our environment with your donation, and protect your Operators with Purestream. Everybody wins!

Increase Trust to 50.When Operator Purestream first joined Rhodes Island, many people did not understand the purpose of the things that she insisted upon.
Such an outcome was not unexpected. After all, Purestream came off as energetic but naive in the eyes of more experienced Operators. Even though she knew a little bit of Originium Arts, she has never experienced the cruelty of bloodshed or the sorrow of lost lives. This cheerful and lively personality may make her easy to get along with, but earning the trust of others is a much higher hurdle.
Back then, very few people understood the importance of the "environmental conservation" that Purestream was always talking about. After all, between Catastrophes, Oripathy, and Reunion, there were too many threats that were considered more imminent.
But after Purestream quietly cleaned the waterway around the area Rhodes Island was stationed as well as handling the after-treatment of Rhodes Island's sewage in the process, some sharper-eyed Operators began to understand - this youthful water treatment worker may not be so good at combat, but the work she does do is more important than anyone would expect.

Increase Trust to 100.We do not find a lot of information regarding Purestream's hometown.
This is not to say that we ran into many difficulties during our investigation, but after reviewing the material, there simply weren't many things worth keeping. Purestream's hometown is a small, simple village located close to a river. Famous for its pure, clear water, this village has retained many customs that reflect the simplicity of the past. Catastrophes rarely affect this area. Relatively isolated from the outside world, the people here have not had exposure to the Infected, have little conception of Oripathy, and are not wary of outsiders. When asked by our investigators about these subject matters, they were quite open with us, viewing these issues as no big deal.
We found that Operator Purestream worked with Rhodes Island personnel to resolve an issue involving an Originium discharge causing downstream pollution in this local river. After this incident, she became the talk of the town, with many seeing her as a bringer of good fortune. Apparently, she felt the limitations of her own abilities during this incident, and decided to contact Rhodes Island with hopes of expanding her horizons.

Increase Trust to 150."Conserve water. Yes, it's good to conserve water, but we still get to keep the large bathtub, right?"
Due to the characteristics of her race, if Purestream is in a dry environment for extended periods of time, she may experience skin discomfort. In severe cases, allergic reactions, chafing, or other related symptoms may occur. Therefore, Purestream always carries a small spray bottle of purified water with her. She can often be seen taking out this bottle to spray water over her face. Rhodes Island's well-equipped bath facility has quickly become one of her favorite places.
Purestream holds herself to strict standards in the conservation of resources, her conviction only faltering when it comes to her bathing problem, for which she appears ashamed and apologetic about.
For others, this is perfectly understandable, for nobody is perfect. Despite that, Purestream has expressed remorse for her actions and has even set up a rule that limits her to three baths a day.
Because of this restriction, she makes sure to thoroughly enjoy each session. When she completely submerges herself into the water, the young girl is so happy that she sometimes can't help but to sing.

Regarding Operator Purestream's race, it is difficult to find out where they originated from, but we may be able to glean some clues from some local folk songs.
Her true hometown must be very far, far away, in a distant land.

Well, it seems like there are no problems with your certification, and the sewage treatment seems good enough... It's good that you're a law-abiding organization! |
| Talk 2 | Woah, this water tastes amazing~! It's cool and sweet, just like the springs back in my hometown... Where's the water source? How is it filtered? What are you using to filter it? Please tell me quickly, Doctor! |
| Talk 3 | There are signs of excessive wastewater discharge this mon-- Huh? Did I take too many baths again? ...Oh no, I must reflect upon my behavior! |
| Talk after Promotion 1 | I love my hometown! Although it's not as lively in the country as it is in the city, and daily life isn't as comfortable, the water there is cool and delicious, and the air is always fresh. Hehe, these are sometimes hard to come by in the city! |
| Talk after Promotion 2 | The pollution near the city is getting worse and worse. Earlier, we even had problems with the water supply in my hometown, and resolving that situation required a lot of effort. While Catastrophes pose a very clear threat to us, pollution will also erode away at our habitable spaces! Therefore, protecting our environment is also of great importance! |
| Talk after Trust Increase 1 | Heave, ho! That should be the last shoe... Got it! Phew, now, this waterway will be much cleaner, and my daily efforts here won't go to waste! Thank you for accompanying me, Doctor! |

| Talk after Trust Increase 3 | Back in my hometown during harvest season, each family will make lots and lots of delicious food! Braised, sweet and sour, steamed, fried, marinated, anything you can imagine! Doctor, why don't we go visit together? The people there are very hospitable~ |
| Idle | Ugh... So dry... I want to soak in a bath... |
| Onboard | Hello, I am the municipal waterway cleaner, codename Purestream! From now on, I will handle the water treatment and sanitation of this ship, so please rest assured! Oh, these are pickled vegetables from my hometown. Everyone is welcome to try some - I assure you, it's delicious! |
