Kuoh Town, Hospital.
A young man awoke from a hospital bed.
"A strange ceiling."
Getting up from the bed and scanning his surroundings, Tatsuma began to ponder life.
Who am I? Where am I? What am I supposed to do?
If he remembered correctly, after working overtime for a month straight, he finally got approval for two and a half days of vacation. To celebrate, he had stayed up all night playing games yesterday.
How did he end up in a strange place after waking up?
Just then, an unfamiliar memory surged into Tatsuma's mind.
After digesting all of this memory, Tatsuma successfully understood the current situation.
Simply put, he had transmigrated.
The owner of this body was also named Tatsuma.
Not long ago, Tatsuma's father was promoted. To celebrate, the family drove out to a nearby restaurant for dinner.
On the way, Tatsuma's family was caught in an explosion. Tatsuma's parents died, and Tatsuma, the only survivor, suffered many injuries and mental trauma.
Just now, the original Tatsuma passed away from excessive grief, and the transmigrated Tatsuma took over his body.
Tatsuma's expression was a little pained.
Because he was a transmigrator, he didn't feel much about the death of the original Tatsuma's parents. What truly made him feel bad was the culprit of the explosion in the memory: a black monster about two meters in size.
That's right, this world contained supernatural monsters.
Although Tatsuma didn't know what that monster was, or why the original Tatsuma's parents and other people around couldn't see it, it was indeed that monster that attacked Tatsuma's family, which then caused the explosion.
The original Tatsuma was judged to have mental trauma because the people around him kept thinking he was talking nonsense.
"This is troublesome now."
A world with monsters, and he was even one of the victims.
No matter how carefree Tatsuma was, he inevitably felt pressure.
But just then, a voice rang in his mind.
[Ding! Trait System has finished loading. Please click to view its specific functions!]
Tatsuma's eyes lit up.
Following the new information in his mind, Tatsuma opened the system panel.
[Tatsuma Nakamura]
[Race: Human]
[Strength: Level 1]
[Traits: Spiritual Vision (White), Spiritual Healing Bracelet (Blue)]
[Spiritual Vision (White): You can see abnormal existences that ordinary people cannot, but that is all.]
[Spiritual Healing Bracelet (Blue): You are the holder of the Sacred Gear Spiritual Healing Bracelet. Activating it can quickly restore your own or others' injuries.]
'Sacred Gear... So that's it, I was able to recover so quickly from the explosion thanks to this thing.'
Tatsuma thoughtfully examined the panel.
These traits represented his talents or certain characteristics.
According to their grade and effect, traits were divided into seven levels: White, Green, Blue, Purple, Red, Gold, and Rainbow.
The higher the trait level, the better the effect.
With the trait system, Tatsuma could perfectly control all his traits.
"Is this the Spiritual Healing Bracelet?"
Looking at the white bracelet that had appeared on his wrist, Tatsuma activated it.
A white light surged, and the injuries on his body, which had not fully healed, began to recover rapidly.
"It's a bit exhausting."
Feeling the weakness coming from within his body, Tatsuma quickly stopped the Spiritual Healing Bracelet. The effect was really good, but the consumption was equally astonishingly large.
[Host has successfully activated a trait effect once, rewarding a Starter Gift Pack.]
Such a good thing?
Tatsuma opened the starter gift pack.
[Opened Starter Gift Pack! Congratulations on obtaining the Rainbow trait Limitless Potential.]
"Hiss..."
Rainbow trait!
This was already the highest level.
Looking at the system panel, Tatsuma quickly checked the effect of the new trait.
[Limitless Potential (Rainbow): Your potential has no upper limit. As long as you train, you will become infinitely stronger.]
Limitless Potential, no upper limit to potential.
"Looks like I need to train hard."
The experience of being attacked by the black monster lingered in Tatsuma's mind. Knowing that such monsters existed and having the opportunity to become stronger, Tatsuma was full of drive.
Getting up from the hospital bed, his body already fully recovered, he went to complete the discharge procedures.
Back home, Tatsuma immediately ordered a batch of fitness equipment and began to train diligently.
With the Spiritual Healing Bracelet, he didn't have to worry about injuries, so he trained with high intensity every day. In just one week, his muscles had already become well-defined, and his abdomen even gained an eight-pack.
In addition, by self-studying through videos, Tatsuma successfully got started with kendo and close-quarters combat, and each training session brought him new insights.
"As expected of a Rainbow trait, the effect is amazing."
Tatsuma initially felt the power of Limitless Potential. It not only greatly improved his training results but also significantly increased his understanding, making him astonishingly fast at learning new knowledge.
However, just as Tatsuma was about to continue training, a call from the school came to his home. After some communication, he learned that the school had received his discharge notice but found that he had not returned to school.
Worried that he might have health problems again, they called to inquire about his situation and to ask if he wanted to continue taking leave to rest.
Tatsuma originally wanted to continue taking leave, but after carefully recalling the school situation, he suddenly realized something.
The school he was currently attending was called Private Kuoh Academy. There was a senior named Rias Gremory, a good friend in his class named Yuji Itadori, and his teacher was named Natsuki Minamiya.
"Wait, this isn't right." Tatsuma rubbed his forehead.
Recalling carefully, he found that besides these people, there were many other familiar names in the school.
"Did I transmigrate into an anime?"
After transmigrating and being engrossed in training for a week, Tatsuma finally belatedly realized the truth.
The world he transmigrated to was a grand mashup world, a mix of various strange worldviews.
