//Backstory Explanation
Lymph is a defective magic user. She wasn’t able to produce any high T magic so she roams around as a single B magic user, releasing NTB0D1-sprites and signals help from T magic users to the scene. She tries to join other WBC Squads as a means for her to work or else she doesn’t have any food to eat.
Although her main objective was to work to cover her own expenses , she also wanted to train herself and prove to others that she had potential to be in at least 1 T magic type. Maybe just like the top ranking T cell magician , Great Magia Black Moon
She figured that she could try her luck of getting recruited at the soldier’s base which is where she met Neut on the outskirts of town , right before the fungvir forest. He teams up with her without knowing that she couldn’t use any T magic . Neut was particularly strong but since he was the over-confidant type of person , his old team couldn’t stand him.He tags along with her to fight strong enemies but she also wants to learn how to fight like him.
Next she meets with Eosin (Osin) . He was cornered by large parasite monsters during the Allergerain war . His squad died and he was the only one left . Lymph and Neut registered as the rescue team ( seeing that Lymph is a B magic user , she could at least distract the enemy or call for T magic user).Eosin joined the party as he can't return to the city or else he will be branded as a deserter
Then the trio met with Basof . He is an extremely strong histamine user, capable of saving an entire village from burning down. But since his magic was too strong, he was always the subject of envy by his squad so they planned to kill him off in a fire by making him get caught in his own magic, thus burning himself. The trio managed to save Basof but his appearance was burned quite badly . His old squad must have reported back his death so now he lives on as a dead man. The trio recruited him .
Lastly , they met Mono. She was fending off a group of Kuppfers , a mutated species of fetal macrophages that migrated to Liverlake . They tried to help out but they were caught off-guard and were almost killed by the enemy until she came along and defeated them easily.She was getting bored of doing solo missions and decided to help them on their journey in exchange for food.
It is revealed much later that Mono is the Great Magia Black Moon but she hates the title as most would fear her instead of believing in her goodwill.
// Video Explanation
The song starts off with Mono as the main character and as Great Magia Black Moon. The scene is much darker due to her personality that tends to be more negative but she still has good intentions to protect and save Hsapia. She is placed at the back as a symbol to look over everyone and that she might learn something from the new generations of W.B.C corps.
After introducing the other characters , the screen shows a Game Over scene as to show that if we keep the old way of retaining justice in Hsapia, Mono would slowly succumb to despair due to the countless enemies she has to defeat alone .
The scene rewinds back to the start and Lymph has taken over the role of Main Character. The scenes appear much more brighter and the team is seen more clearly although they are the exact same scenarios , Lymph’s outlook on her journey is still pure and full of positivity . Despite being stark contrasts of Light (Lymph) and Dark (Mono) , both of them work together to keep Hsapia safe .
Occasionally you are able to see Lymph eyes turning from blue to red , it means that depending on your choices by using her as main character , she can unlock the potential to be “The True Savior” or the “Harbinger of Death”.
