Anime Crossover: Start by Signing In to the Infinite Dragon God

If he truly reached the level of Origin Vishnu, [Krishna] would basically grant him omniscience and omnipotence.

For now, it was more like gaining a buff that greatly expanded his senses. Of course, it was not limited to perception; he occasionally gained some strange knowledge as well.

"Uh... what is she doing outside my door?"

Su Yang finally learned who was standing outside his door.

Even if you were a Maou-class, that was no reason to loiter outside someone else's door!~~

With that thought in mind, Su Yang kicked his bedroom door open.

"Thud!~~" "Thud!~~~"

One sound came from Su Yang kicking the door, while the other was the sound of something heavy hitting the floor.

"Hm? She didn't even try to dodge?"

Su Yang opened the door and saw Serafall sprawled on the floor in a posture of utter dejection.

"Hey~~ hey!~~"

Although her eyes were open, there was not the slightest glimmer in them. He had no idea why she had become like this.

It was like... like she had been played broken? But he had no memories related to that.

"Bang~~"

Seeing that calling her got no response, Su Yang showed no courtesy and kicked Serafall's raised backside.

This strike seemed to be extraordinarily effective. Su Yang had thought she would stop him before his kick landed, but instead, that single kick sent her all the way to the door of the room opposite his.

Under that kick, Serafall recovered from that broken, lifeless state.

"I messed up~~~ I messed up~~ I messed up~~ I messed up~~ I messed up~~"

Serafall gave Su Yang a vacant look, then sank back into her withdrawn state.~

"What did you mess up? What exactly did you do?"

Su Yang asked in confusion. Even if she had messed something up, there was no need to shut herself away like this, right? She was a Maou-class, for goodness' sake.

"This time!~~ This time, Sona-chan definitely won't acknowledge me as her Sister anymore!~~~"

Tears filled Serafall's eyes as she emerged from her withdrawn state and looked at Su Yang.

Then her expression collapsed even further.~~~

"Ah~~~ Sona-chan!~~ Don't abandon your Sister!~~ You can do anything you want to Sister!~~~"

As she spoke, Serafall sprang up from the floor and darted out of Su Yang's home, vanishing into the distance!~

"Uh... what... what exactly happened?"

A bead of cold sweat trickled down Su Yang's forehead. Serafall had shut herself away? What had she done to make Sona angry?

[Master, I think it should be because of what happened last night. After she came to Master's room yesterday, she remained in that state.]

The crest representing Esther on the back of Su Yang's hand flickered with white holy light.

"She came to my room last night? What did she do?"

Su Yang frowned, a thought suddenly arising in his mind.

[Yesterday, that woman put some red things into Master's body. I wanted to stop her, but Master's body did not have enough Spiritual Power to give me the strength to drive her back.]

"Then why didn't you tell me when I woke up this morning?"

[Because... because I forgot.]

"Pfft~~"

"Forget it. Were the things she put in something like this?"

Phantom images appeared in Su Yang's hand, the various pieces from a chess set.

[Yes. Six of these, plus one of this and this...]

Esther pointed out which pieces Serafall had put into him yesterday.

After realizing this, Su Yang began examining his own body internally.

Although the power of the Devil Chess Pieces was very faint, there were indeed six Pawn pieces, one Rook piece, and one Bishop piece inside him.

"She actually secretly put Devil Chess Pieces into my body? She really had the nerve to do it.~~"

Su Yang gritted his teeth, feeling that merely kicking her backside earlier had been far too lenient. He should have given her a thorough spanking!~

Was Devil Reincarnation something that could be done in secret?

"But I don't feel like I've become a devil at all. The demonic power in my body also feels like only a tiny fraction of my strength. Combined with what she said about messing up, that means... the reincarnation failed?"

"How ironic..."

Su Yang smiled. Sona would probably pull Serafall's ears off this time.

"Forget it, I should go to school first. I wonder whether Sona already knows about this when I see her today."

Su Yang smiled, tidied himself up, and prepared to go to school.

"Hm?"

As he entered the living room, he noticed a small item there.

"Is this supposed to be a keepsake she left behind?"

It was a pink Magic Wand.

Of course, unlike the Magic Wands used for ordinary cosplay, Serafall's Magic Wand could cast skills. Though they were not particularly powerful, it contained many useful spells and Magic Formulae.

"I'll take it as compensation for now... Once I'm strong enough, I'll settle today's score."

Su Yang narrowed his eyes and placed the Magic Wand in his room.

Once his raw strength reached the Intermediate Devil level, he should be able to understand, analyze, and ultimately learn the Maou-class Magic Formulae on this Magic Wand.

"Let's go, let's go, time for school~~~ There's still one sign-in left."

Su Yang was still in quite good spirits, perhaps because he had gotten so many Devil Chess Pieces for free yesterday.
