Start by Signing In to the Infinite Dragon God

Su Yang could always feel her burning gaze. Having always lived alone, with at most a housekeeping service hired on weekends, he found it a little hard to get used to.

"By your command~~"

Licking her hand again, Amano Yuma's eyes no longer held the innocent purity she had displayed while concealing herself. Instead, they were filled with seduction.

Of course, if she wanted to switch modes, she could easily return to being that innocent young girl.

Come to think of it... the hand she was licking was the one that had touched Su Yang earlier.

This had gone a little beyond the scope of faith. Mm... calling her a pervert would be absolutely no problem.

"Now!~~ Happy study time begins!~"

Without Amano Yuma's gaze upon him, Su Yang finally resumed his studies.

He took out Ajuka's Crystal Ball and began studying again.

The later lessons were a little more difficult than the basic tutorials from before.

"Compatibility and coordination between Immortal Arts and Arts of the Way... an overview of Norse Magic and Elven Magic..."

"Configuration and application of Multi-Layered Sealing Arrays... comprehensive use of Demonic Power Traits... the transfer process of Soul-Type Sacred Gears..."

Sure enough, studying made him happy.

It gave him the feeling that he was becoming more and more fulfilled. The most reassuring thing was not money or status, but the power to protect everything.

"They even gave me this. It seems they trust me quite a lot."

Su Yang narrowed his eyes as he spotted a topic—whether Demonic Power and Holy Power could operate together.

"Aren't they worried I might learn something and infer that the God of the Bible is already dead?"

While Su Yang studied, Amano Yuma was also watching her new master.

"Ah~~~ How sacred, how wise, how overflowing with charm and intellect—this is My Lord~~~"

Amano Yuma had completely poured all the passion and faith she had once held for Asachel onto Su Yang!

"Oh!~~ Right, according to My Lord's will, I need to become a qualified maid!~"

Amano Yuma suddenly remembered something important.

Since living for her master was the entire meaning of her existence, she had to complete her task!~~

She swiftly pulled out her phone. Though she was a Fallen Angel, she still knew how to use useful items from the Human World.

"This!~"

An article caught her attention.

How to Train a Perfect Maid

"Good! This is it!"

Although she was not yet a perfect maid, one day she would become one!~

Amano Yuma... set such a goal for herself.

Elsewhere.

Having fully entered study mode, Su Yang naturally failed to notice Amano Yuma's gaze.

Study time always passed quickly.

However... something pulled him out of his focused state.

"Boom!~~~"

A dragon's might came from nearby!

"This presence is... the Red Dragon Emperor's presence!"

Su Yang narrowed his eyes. Had something happened to Issei Hyoudou?

[Eighth Incarnation: Krishna!]

Switching to his Eighth Incarnation, Su Yang extended his senses to their limit and detected the Red Dragon Emperor's condition.

"This situation is... this situation... could this be an event Issei Hyoudou was destined to encounter?" Su Yang shook his head. You really are unlucky enough, Issei Hyoudou~~

"Yuma, I'm going out to take a look. Just stay at home."

Without waiting for Amano Yuma's reply, Su Yang stepped forward and vanished from the house.

"Welcome back, My Lord~~"

Amano Yuma said respectfully as she knelt on one knee.

Using the power of [Vamana, the Dwarf], Su Yang arrived at Issei Hyoudou's home in an instant.

"Ha~"

Looking at Issei Hyoudou lying in a pool of blood, Su Yang could not help but sigh. He had clearly gone on the date with Amano Yuma in his place, yet Issei had still failed to escape the fate of dying.

Given his current injuries, even if Rias used a Devil Chess Piece, she probably would not be able to save him.

Strictly speaking, Issei Hyoudou was already a corpse. Even the Red Dragon Emperor was leaving his body, which was why its dragon's might had leaked out.

"You should go back first," Su Yang said calmly to the Red Dragon Emperor.

"Hah? Are you joking, kid?"

A trace of disdain appeared in the Red Dragon Emperor's emerald-like eyes.

Even the strongest healing magic would be useless in this situation, unless he could immediately produce Phoenix's Tears. Could this kid possibly have something like that?

Besides, it had long wanted to leave this incredibly weak host. With this host, it would probably lose its next battle against that white guy.

Of course, if this host awakened, it would certainly fulfill its duty as a Sacred Gear and combat partner.

"I said... you can just go back."

Su Yang repeated himself.
