[Tony Stark: So...You transformed into Master Leo and rescued Lu Mingze, is that right?]
[Lu Mingfei:....]
[Zero:....Master Leo told me that, you're probably the best Human Host Candidate ever to exist....A Kind Heart and Stubborn on necessary things..]
[Huo Yuhao: .....When can I become Ultraman, damn it?!]
[Taichi Yagami: You? Emperor of Humans, Why are you a naturally black hearted person joining in?]
[Fujimaru Ritsuka: Suffer you Tyrant!]
[Huo Yuhao: Oh! Come on!]
[Lin Yu: Are we ignoring the fact that the Plot is probably completely screwed up over there on Mingfei's side?!]
[Zero: Technically, already messed up way too much the moment Mingfei awakened early, not to mention now when Master Leo also made a cameo.]
[Lin Yu: How'd you become like this Zero?! Where's the sharp tongued Tsundere young master gone?!]
[Zero: Tsundere's are outdated.]
[Fujimaru Ritsuka: Take that back! Tsundere's are super cute!]
[Tony Stark: Isn't an Onee-san way better?]
[Taichi Yagami: If you guys don't stop, we'll get censored!]
[Huo Yuhao: A super cute and caring kuudere is way better!]
[Lin Yu:....Heh, isn't a super clingy and slightly dangerous Yandere way better?!]
[Lu Mingfei:... Isn't an Imouto type better?! How cute they are!]
[Huo Yuhao: So, you like Renata?]
[Lu Mingfei: ??? You!]
[Lin Yu: Ignoring Mingfei's attempt at a Harem, was this always Master Leo's plan?]
[Zero: Yeah, he cares immensely about Master Astra, so, he planned this after learning about your World.]
[Lu Mingfei: First of All, I am Pure Love! Secondly...Zero! You already knew?!]
[Zero:...I have the right to remain silent]

Moving on from that, Mingfei who was now human sized, holding a recharged Leo Capsule he got from Zero, released Master Gen.
"Phew! You're quite a good child Mingfei, if you decide to one day visit our World, make sure to visit the Main Body over there." Otori Gen said as he then looked at the emaciated looking Lu Mingze.
"Hello~" Lu Mingze greeted cheerfully, finally able to move his original body as he waved, only to have something stuffed into his mouth by Lu Mingfei.
"Cough! Coug-" his body began healing rapidly and seemed to be completely normal within a few seconds, "Life Gold, Quality Guaranteed!" Mingfei said with a thumbs up.
"How much do you even have?!" Mingze broke his defence, even he only had a bit after searching everywhere around the Globe (Enxi and Mai who did the searching:?)
"...." Human sized Life Gold drops, disappeared instantly.
".... Brother! I, Lu Mingze, Pledge my loyalty!"
"No need to worry my young padaw- *ptoo*, I mean Mingze, I have much gold." Lu Mingfei also said as he pulled up Lu Mingze who was still in tattered clothing but seemed much more healthier, after all, a small Life Gold fragment was always healing him now and Mingze knew how to use it too.
"Now, let's go eat something, right Master?" Mingfei asked Otori Gen who was smiling to the side who nodded as Mingze slipped into new clothes similar to the Victorian era cute boy style he usually wore as a projection.

The Next Day,
"LU MINGFEI YOU BASTARD!" Lu Mingze yelled as he was being beaten up by Master Gen in hand-to-hand combat while Lu Mingfei kept throwing boomerangs from the side, a training for Lu Mingze to regain his rusted combat instincts.
So, Lu Mingfei, was having the time of his life! Although this brat hadn't fooled him completely yet, seeing the Lu Mingfei in the novel who was a loser through and through made him throw the boomerangs even harder.
"Messing with your Elder Brother, huh? Making a deal and accidentally capsizing, huh?!" Mingfei kept mumbling as he threw the boomerangs at even faster speeds, making even Master Gen stop and look on as Lu Mingfei's speed kept increasing and Lu Mingze kept dodging.
"As expected, they're truly siblings." Master Gen who always got randomly ambushed by Astra sometimes nowadays said with certainty.
Although, those words did make the former babysitter trio look at him in new light, after all, anyone could see Mingfei's excitement and rapidly increasing power as he kept tormenting Mingze.
Is this actually what sibling love is? Then what's up with the pretty normal sibling relationship between Sakatoku Mai and Sakatoku Aki?!
Moving on, looking at Mingze's disheveled apperance, Mingfei's power was genuinely increasing more and more to keep up with the rapidly recovering Lu Mingze, to the point that they both started to move at faster and faster speeds.
Mingze trying to run with Mingfei chasing behind, both of them getting faster and faster, slowly from 12 times the average human to 15 times to now atleast 20 times.
Mai who was considered a good fighter and top tier combatant was doubting life, because the Little White Rabbit that they had watched for years was now more of a Black Dragon trying to tear apart another Black Dragon, although she can understand her Boss rapidly growing stronger since it's actually just him recovering.
What's up with Lu Mingfei, he's growing stronger at an equally astonishing pace, "Mingfei!" Master Gen shouted as he threw a belt to him, "Go for it!"
"...?!" Mingze's speed seemed to increase by another notch because...he realised that the belt was definitely one with enhanced pain against beings of Darkness like himself and Elder Brother...Oh wait, Elder Brother is more light now! Damn you Brother!
They both knew that Mingze wasn't actually afraid of pain but well, the feeling of wanting to discipline Mingze was something Mingfei was getting addicted to while to Mingze...it was purely embarassing, especially infront of his followers.
______
"....Elder Brother..." Lu Mingze who was lying on the ground and looking at the sky smiled, "Thank you..."
"...Heh, you don't need to thank me....After all... We're brothers..."
"....Is that why you beat me up?" Mingze asked cheekily as he turned his head slightly.
"Of course! It's an Elder Brother's duty to discipline an unruly younger brother." Mingfei said with certainty, making them both laugh.
"....Oh right, you two are still training tomorrow." - Master Gen
"Eh?" x2
Thus, Mingfei successfully completed Part I of his prologue while dragging in Mingze to suffer as well.
What a deep brotherhood that makes one weep!

Meanwhile, Secret Society....
"...What do you mean Ultraman Leo came and took him?!" - A handsome old man asked Giovanna confused.
"...I don't know Principal Anjou." She, a beautiful woman, Giovanna, Mother of Lu Mingfei, also sighed sadly...she knew what this meant...
Lu Mingfei was going to truly become a Weapon of War now that the only leverage they had was gone....
(Master Leo: Who decided that?!)
