Crossover Anime: Building a Demon Familia from Scratch

Seeing this, Lynn took another sip of red tea, keeping his merits and fame hidden.

He was indeed too kind-hearted; he couldn't bear to see his own people suffer!

"found it!"

Kasumigaoka Utaha exclaimed in surprise.

Seeing this, Rias smiled happily and said:

"This magic is quite simple. If you want to learn it now, I might be able to give you some advice."

Kasumigaoka Utaha smiled at her and said, "Thank you, but I don't think we need to trouble Rias-san."

After thanking her, Kasumigaoka Utaha bowed her head again and began writing in the Book of Demons.

Rias was slightly taken aback and looked at Lynn with some confusion.

Why ask about this magic spell? Isn't it just to make copying easier?

Why are you copying it again?

She quickly understood the reason.

"It's done!"

Kasumigaoka Utaha put down her pen, stretched her body, and then released her magic, her eyes filled with anticipation.

hum-

The Book of Demons suddenly shone brightly!

A small white magic circle suddenly appeared on the page that recorded 'automatic writing'.

A white feather pen slowly materialized.

It worked!

Kasumigaoka Utaha cheered inwardly.

It's genuine magic!

Although it was just a trivial little magic spell, it was enough to excite her.

"This is......"

Rias's eyes narrowed slightly.

It truly is the magic of 'automatic writing'.

Did you learn something while copying it?

Or......

The real reason lies in 'copying'?

And that strange book.

Rias thought for a long time, her eyes sparkling slightly, and praised:

"I didn't expect Kasumigaoka to master the magic of 'automatic writing' so quickly. Mr. Lynn's family is indeed extraordinary."

Then, Rias changed the subject and said, "I remember Mr. Lynn's residence is quite a distance from Kuoh Town."

"There's a teleportation spell on page 777 of that book. Why don't you learn it now and leave a mark here for future reference?"

Kasumigaoka Utaha's performance piqued Rias's interest.

She wanted to see whether Kasumigaoka Utaha's learning ability was strong, or if it was some kind of special ability.

Although the teleportation magic on page 777 is a common skill in the underworld, its difficulty is definitely no less than the family secret techniques of some demon nobles.

Even she spent a long time studying diligently back then.

She didn't believe that Kasumigaoka Utaha could master this ability in such a short time.

Lynn saw through her plan at a glance, but instead of stopping her, he added fuel to the fire by saying, "Shiyu."

Although they had only spent a little over a day together, Kasumigaoka Utaha understood what Lynn meant.

She turned to page 777 of the black book.

'Magic Cube Jump'.

Without pausing, Bai Yubi began copying from the Book of Demons.

Rias didn't have to wait too long.

The moment the white feather pen stopped, Kasumigaoka Utaha, who had received Lynn's instruction, immediately released her magic.

hum-

A purple magic circle, dozens of times larger than before, rose above the Book of Demons!

The dense array of runes was so numerous that it made one's eyes dizzy.

At least Kasumigaoka Utaha didn't understand what those runes meant.

But it doesn't matter, she doesn't need to understand!

This is the devilish Party Secretary!

Rias stared blankly at the 'Magic Cube Jump' magic circle, slightly lost in thought.

His eyes were filled with disbelief.

You actually... learned it?

In such a short period of time?

Even Akeno Himejima and Koneko Toujou were drawn to it.

As Rias's familiars, they also mastered the 'Magic Cube Jump', and therefore understood the difficulty of this magic even more clearly.

A familiar who appears to be merely an ordinary person reincarnated into a demon has mastered a highly difficult spell in an extremely short time, even though she has only just entered the world of the extraordinary.

If it's just through learning, then it can be described as having extraordinary comprehension.

But it's clear that Kasumigaoka Utaha didn't 'learn' it.

Rias focused her gaze on the book, a smile unconsciously playing on her lips. "What an interesting ability."

"Copying, or rather, recording, documenting?"

"As long as the knowledge is recorded in that book, it can be mastered."

Lynn clapped and said, "As expected of the eldest daughter of the Gremory family, she has grasped Shiyu's abilities so quickly."

"Let me formally introduce myself, Secretary Demon, Kasumigaoka Utaha."

“Secretary Demon…” Rias murmured, then said, “A very fitting title.”

Rias took a deep breath and then tentatively asked, "I wonder if Mr. Lynn would be willing to reveal the limits of this ability?"

Record everything, control everything.

If it really is that powerful, Rias would not hesitate to categorize it as a God-Slaying Tool.

Lynn rested his chin on his hands, a slight smile playing on his lips. "The limits, I'm not quite sure either. Why don't you investigate, Miss Rias?"

A book on general magic usage techniques is hardly enough to satisfy him.

It's time to unleash your skills, Lady Gremory.

P.S.: I need the data!

P.S.: Thank you for the monthly pass!! Thank you for the flowers!!

Chapter 9: Mana depletion? Time to replenish mana.

"I see. Is that why you had Kasumigaoka demonstrate her abilities?"

Rias suddenly realized, then looked at Lynn with a complicated expression.

Was this also part of your plan?

Lynn gave him a look that said, "You've caught me."

Common skills are simply not enough to satisfy his appetite.

He flipped through that black book a few times as well.

It can only be said that there is too much theoretical knowledge.

There's also a lot of repetitive content; it's incredibly long and tedious.

The remaining magical abilities are all very ordinary things like 'automatic writing' and 'lighting'.

The most valuable one is probably the 'Magic Cube Jump' teleportation spell.

As for those that are powerful, have a wide range, and are highly practical, there are practically none.

Since he was already there, Lynn naturally wanted to learn some powerful skills.

Therefore, when he saw that Rias was curious about Utaha's abilities, he naturally went along with it.

Whether there are dates or not, let’s take a shot first and then talk about it.
