We are lucky enough to receive the support of the Lumo Knights. Ms. Raphael, one of the Four Angels, prepared a grand welcoming ceremony for us on the day we boarded the ship. Although we should be the ones holding a welcoming ceremony for her, the opposite happened for some reason.
We still remember the joyous events of that day as everyone was given a Top Secret Divine Dust-repelling Holy Water shell and was chased everywhere by it... I can only say that we were lucky this welcoming ceremony wasn't held on our ship.
There are some other things about her that have left a deep impression on me. For example, she seems to have some sort of... mechanical wings? On both sides of her cute dress to help her keep balance. She also has a giant mechanical cross... I bet she uses that to shoot those homing Holy Water Shells!

I'm one of the Four Angels of Lumopolis, and I am both an ambassador and a knight! My duties are much easier in this peaceful age as I mainly need to conduct patrols and maintain law and order. I also occasionally accept small missions to eliminate enemies and spend a lot of my time on medical activities and medical research. But the Eclipsites have resurged again recently, which is really annoying as I have to take time from my medical activities to deal with them! I want to do whatever I can to help you fight those annoying Eclipsites. Now that everyone is on bad terms and can't unite, it's actually easier to join you and take action together!
You don't need to worry about your old injuries at all. One bottle of my healing holy water and I guarantee that your waist and leg will feel as good as new! If patrols are comprehensive and treatments are perfect, you'll be able to complete more missions and even go out to search for news!

You can trust my ability completely! Listen to that boom! Today's lantern is also full of firepower! I've especially borrowed the power of Illumina Tech to give my patients better treatment. This Holy Water Shell isn't any old shell. It deals damage to enemies and heals allies! If I want to know whether you're a friend or a foe, all I need to do is to shoot this at you. I mean, extraordinary times call for extraordinary means!
Occasionally, someone's bones will be broken by my Holy Water Shell, but it's actually quite easy to fix—I just need to treat them with another type of holy water. As for the mild burns covering their body... they'll be fine as the burns will heal naturally after some time! As they say, doctors can heal, but they can also kill... Huh? That's strange... I don't think that's right... Either way, you'll find me wherever there's a patient to treat!

After John's med unit was disbanded, Gabriel and I went to Lumopolis. Gabriel told me that I'll be able to heal even more people if I joined the study exchange program with Illumina! Since I have nowhere to go after the medical team disbanded, I'm happy to go to any place where I can learn more treatment methods!
The R&D staff at Illumina told me I was an incredible genius and helped me remodel my master's relic out of the kindness of their hearts. Yes, it is my cross that is filled with holy water!
I also invented the holy water series myself, but they were just ordinary medicine at first. I thought about it and decided that it would be too simple if they are just medicine, so I remodeled them into this versatile Holy Water Shell! Raphael even made me one of the Four Angels because of this!
What's that? That's not it?

From a young age, my master taught me that everything exists for a reason, so we must save as many lives as we can!
I have followed my grandfather—who was also my master—since I was a child! I admired all the young men and women of the medical team at that time! They had superb medical skills and had to deal with the battles that could happen at any moment! So, I made up my mind at that time to work hard to become someone useful like them!
Whenever I work with everyone to save civilians who are tortured by injuries and illnesses, I feel so satisfied whenever I see the grateful look on their faces!
... Later, there were many times when I woke up in the middle of the night, only to see my very old grandfather grimace in pain due to his injury... He must have been forcing himself to pretend to be fine in front of everyone else because he doesn't want others to worry about him... So, I followed my grandfather's instructions and made him the pain-removing holy water and helped him drink it so that he could go to the stars first and wait for me up there! I'll join him there one day!
