Several days later, outside Japan.
"Do you think we can enter undetected, Zeoticus?"
Asked me Grayfia as we stood outside Japan.
Entire Japan was enveloped in the enormous magical barrier, whose purpose wasn't blocking entries but rather scanning being and undercover those with magical power and alerting Shinto about them entering Japan.
The barrier itself would activate the moment it detects somebody with magical power, currently Unit. With this method, Shinto has practically covered the entire nation and absolute control over who entered and left the country.
"We can, such big barrier, unless created by someone on Apocalypse-Class with expertise in this type of magic or God with Divinity over Magic at Mighty Stage God, will have some weak spots. We just need to find them and disrupt the flow of magical power in the barrier, and we can enter."
I explained as I cast a detection spell, and Grayfia did the same as I taught her some spells.
Several hours later, it was Grayfia who found the weak spot in the formation.
"Good, and now we will do this."
I said as I used some magical power to disrupt the flow of the formation in the weak spot.
"Quickly enter... it won't last longer than ten seconds."
I said as I unleashed my ten wings, flew through the spot, and entered Japan, with Grayfia flying closely behind me. As we entered the place, the barrier soon continued operating normally as it repaired itself rather quickly.
"Now, where are we?... Kyushu... we need to get into Kyoto."
We were in Kyushu, which is not so far from Kyoto, at least not far from the supernatural beings that could cross great distances within one day. For example, I, at my top speed, could easily travel through the entire planet within 6 hours, as Draconic Deus wasn't a large planet.
Kyoto is the Imperial Capital of Japan and also the Spiritual Capital. It has the highest concentration of the Youkai, Gods, and other supernatural beings in Japan. The reason for that was that the main entrance to the Takagahamara Realm was located there.
Contrary to the Nine Realms, Takamagahara wasn't a Dimensional Pahtneon World. Still, rather it was originally naturally born pocket dimension that later became something akin to a divine world when many gods of Shinto infused their Divine Kingdoms into that pocket dimension, giving birth to the Takagahamara.
The origins of Olympus were the same.
"We should move... Kyushu is close to the place where forces of Church and Angels are concentrating... we should look for them. They should send maximally someone or two Cadre-Class Angels, which I should be able to handle, while you will take care of weaker angels. No one can survive."
I said with a bloodthirsty voice as I could not wait to spill the blood of some angels. Grayfia just nodded and flew behind me as we were searching for angels that were in Japan. As we were flying through the lands of Japan, I observed the country itself.
Medieval Japan was an absolute shithole. The current year 1414, around 50 years before the start of the Sengoku Period, or the commonly known Warring State Period, where Japan was engulfed in constant wars for about 150 years.
"Land down."
As we landed down and went by foot, I said as I felt some disturbances through detecting spells. Currently, it was deep night, so it was a time when most Youkai were active, and some malicious would often hunt for humans as their prey.
We were walking for about twenty minutes before I stopped and took out my scythe Rosenkreutz. I silently chanted a spell, a Strategic-Tier Spell [Hell Flame], as dark red flames materialized out of nothing around my scythe. When they grew to sufficient size, I released them in a full might around my surrounding, burning down everything in diameter of two hundred meters.
After the dust had settled, I looked around and scanned the area.
"Ohh, not dead yet?"
I muttered in surprise as I looked at the half-charred body of Onis that were following us. All of them were Ultimate-Class beings in terms of physique, meaning they were pretty strong.
"They were following us?"
Asked Grayfia, surprised and ashamed at the same time that she couldn't detect them.
"Indeed. You don't need to worry that you cannot detect these guys. In their home turn and during the night, they are strongest. Not to mention that they can use Negative Energy during the night to boost their strength even more. These ones should be some rogue Onis."
I said as I swung my scythe and ended their pathetic lives. At the same time, I used Devour to absorb their Life Energy, as it would help my physique.
[Life Energy of 4 Ultimate-Class Oni absorbed. Physique collectively increased by 15 points.]
Each of my physical attributes was increased by 5 points. My bad for killing these guys in so a crude manner and not killing them instantly; it wasted too much precious Life Energy.
Oni were species similar to devils living in Japan and its affiliated realms. They were a race of negative energy and were often regarded as evil spirits. They looked mostly humanoid, with one or two horns on their forehead.
Contrary to devils, who were more inclined to Energy Training and magic overall, Oni was a race of physical warriors. Rarely were some Oni spellcasters or magicians, and all of them were warriors and were extremely dangerous in close combat. For them, it was very simple to reach Ultimate-Class in physique, as long as they trained for several decades.
Onis that were tailing us were rogue ones, meaning they were kicked out of their tribe or clan for committing some crime. They probably felt that we were reeking negative energy and wanted to kill us so they could eat us and get stronger through eating us.
Similar to devils who could eat souls, Oni could get stronger from eating the flesh of beings of negative energy, such as devils.
