The yellow flash of jujutsu high

Time skip.

After being cursed from reading those dam, horrible, horrible books that he will never touch again a day in his life.

Keitaro was back again in his house, currently, the two were seen sitting next to each other sitting in a very nice silence.

He was currently writing down notes in his notebooks as one good man would do.

He had ideas of stuff he wanted to check out and so on.

"You look like you been to war" Shoko added upon noticing the way he would shiver from time to time.

"Something close to that" He replied as the memory of what he had heard still haunted him to this day.

Shoko easily figured out that this was probably one of Gojo's pranks, Though she did wonder what Gojo showed him to shake him that much.

Shoko's eyes landed on the beer cabinet where 5 beer bottles could be seen.

As she was about to go get them, she heard Keitaro's voice say.

"No..."

She turns her gaze to look at him as if to ask him why.

"Not dealing with drunk Shoko..."

"Is someone afraid" She teased looking at him.

"Aren't you the fastest sorcerer alive, There is no need to be afraid of a drunk nurse"...

She truly was trying to gaslight him.

"Satoru my friend.....Your gaslighting skills are far below his..don't ever try it" Were the words that left Keitaro's mouth.

"But...Booze!"

She looked like a lost puppy being refused food, booze was good, how dare he refuse her such a wonderful thing.

"No Booze for you" Keitaro replied to which she sighed, well time for her to find a way to entertain herself.

Her eyes landed on the book he was scribbling on...She was curious.

"Can I take a look?" She asked.

He politely handed her his notebook.

She opens the notebook.

Keitaro's Notes – Cursed Energy Optimization & Spatial Technique Development

Cursed Energy Flow Enhancement:Issue: The current technique (teleportation) creates significant strain after consecutive uses.Solution: Need to regulate energy flow more efficiently to reduce fatigue.

Test Idea: Develop a steady, thin layer of cursed energy (the natural energy layer already helps) to distribute power more evenly.

Drawback: Potential energy leakage—must find a way to contain output without weakening technique strength.Barriers and Seals for Energy Conservation:

Concept: Barriers used traditionally to trap enemies or defend oneself could also be applied to cursed energy retention.

Modification: Use miniature barriers within the body as internal "storage" points. Helps conserve energy without requiring constant external output.Note: Could be combined with the natural energy flow I've been working on to reinforce stability.

Design Idea: Circular seals etched into key chakra points. {Those chakra points are the spinal column, between the eyebrows, centered in the heart, and the abdominal region}

Test Application: Try applying seals to forearms and calves first—areas frequently used during movement and attacks.Must be invisible during combat (keep it seamless).Spatial Technique: Expansion of Control

Goal: Refine teleportation ability (Cursed Flash Step) for more precise control over personal space in combat.Problem: Current teleportation is limited to direct line of sight and marked points.New

Concept: Create "pockets" of controlled space where I can dictate movement, speed, or even freeze opponents' attacks mid-air.

Steps to Work On Zone of Control: Must be able to summon a field up to 5 meters wide around me, controlling the flow of energy within it. Start by limiting the range to 1.5 meters until the technique is refined.

Energy Efficiency: Will need to draw energy directly from nature or the surrounding environment to fuel prolonged usage.Note: Natural energy flow must be further stabilized to ensure consistent output during long battles.Improving Teleportation Consistency:

Problem: Rapid consecutive teleports (Flash Steps) cause afterimages to blur or dissipate too quickly.

Solution: Adjust the way afterimages are created—perhaps by manipulating time distortion instead of raw speed.

Additional Note: Cursed Seal Marking is helpful, but feels limited without stronger seals. Consider developing a "double layer" seal for more accurate teleportation targeting. Test Notes (Barriers/Seals):

First Attempt: Small-scale internal seals applied to hands—too much leakage, couldn't maintain energy.

Second Attempt: The natural energy layer controlled the leakage, but the cursed energy reserve depleted faster than expected.

Conclusion: More precision is needed in balancing cursed energy vs. natural energy reserves.

Shoko felt like she was reading through a comic book as from time to time there would be a small doodle telling her what to do and not do.

The doodle would look like a mini Keitaro. She could see the diagrams alongside the hastily scribbled arrows pointing to different parts of the body.

Keitaro had even added small annotations here and there, reminding himself to "focus on chakra balance" and "watch out for energy burnout."

Shoko paused as she came across a fresh page, it looked a bit recent....like a few days old. The reason she could tell that was because the doodle on the page looked to be quite refined as if the person drawing it, was getting more experience with drawing doodles.

It was either that or the 11/10/2010 on the front of the page. Considering the day she was reading this was the 16, it should have been about 5 days since whatever had happened to make Keitaro write down this note happened.

Keitaro had outlined a human body, with specific points marked along the arms, legs, and torso. He had labeled them "potential seal points" and drawn lines connecting them to the head, marked "main control center." Beside it, he'd written a note in bold:

Marking myself allows for instantaneous travel through warped space. In combat, this gives me an edge by ignoring distances between myself and my target. Testing needed: If I place a mark directly within Gojo's Infinity barrier, does it still work? Can I bypass Infinity entirely by marking Gojo himself? Hypothesis: Since my teleportation doesn't rely on moving through space in the traditional sense, Gojo's divisions should be irrelevant. Teleportation essentially "skips" the layers of Infinity.

Page 5: Infinity Bypass Theory

Principle: Gojo's Infinity creates infinite divisions between objects. My marks ignore space and allow me to bypass those divisions. A recent test in a fight with Gojo: Marking myself allowed me to cut through the Infinity and land hits. Potential to replicate on a larger scale.Goal: Develop a permanent mark-based technique that functions like a seal in this zone-like state. This would serve as a solid counter to Gojo's Infinity, even in prolonged battles.

Page 6: Zone State Replication

During the last sparring session, I entered a zone-like state where I could move fluidly between marks and ignore distance altogether. Replicate that feeling, possibly through meditation or a specific mental trigger. Idea: Replicate the sensation with a seal that forces spatial awareness to shrink to zero. Simultaneously create micro-warp fields that mimic Infinity but at a much smaller scale, essentially creating an anti-space technique.

A/N If I were to write everything in Keitaro note that in itself would be around 100 chapters worth of content if not even more, stuff about Buddhism, Hinduism, jujutsu, curse energy, seal, his curse technique, other people's curse technique.

For Christ's Sake, he has a guide on a step-by-step plan to master the 10 shadow techniques and a way to cheese the living fuck out of Marohaga and one-shot him. The Minimum requirement is to be a grade one, have a domain expansion, and have mastered all the previous Shikigami before Big Raga. Along with very good curse energy efficiency
