When I opened my eyes the first thing I noticed was that I wasn't in the room I shared with my sister; I found myself in a moderately sized room, decorated for a two- or three-year-old kid.
The second thing I noticed was that my body seemed to have shrunk while I slept, because when I looked at my hands they looked like those of a two- or three-year-old infant.
Third: around the room there were different words in Japanese that, after reading them with a little effort, I understood. That only fed the shock in my small mind. On a little sign hanging from the door was written: Katsuki no heya; my treacherous mind translated it as "Katsuki's room." When I read that, I could only rub my eyes in disbelief with my new, tiny hands.
Fourth: suddenly memories of a life I had not lived, belonging to someone else, began flooding me. After receiving and assimilating the memories that invaded my consciousness, I did the most logical thing my shocked mind could come up with.
I screamed, in panic and hysteria.
[TIME SKIP]
I glared at the leaves of the trees in my line of sight, as if they were to blame for the mess crowding my head.
"Stupid leaves," I muttered, angry, at the little leaves. Seeing that they were not going to magically disintegrate from my glare, I sighed. I still couldn't believe the absurd hilarity that only he would understand about this situation.
When I woke up a few weeks ago I thought my mind was playing a joke on me; I found the situation too surreal and stupid to take seriously. So, after my "little" meltdown, I did the most intelligent thing I could think of: I closed my eyes, rewound, and lay back down to sleep. Very smart, right?
Imagine my surprise when I was woken by several shouts and knocks on the door: "Get up, you're missing breakfast!" —not nearly as politely as I put it—. The point is the same: I was in the fucking body of Katsuki Bakugō. A fictional person, created for the entertainment of thousands, the product of a man's imagination, meant to entertain and, incidentally, fill its creator's pockets with cash. But that's another subject.
The main issue was: why the hell was I in the body of a rival from a damn shōnen? After the disbelief, I decided to get through the day relying on the memories of the previous owner of this body, horrifying as that sounded.
It's not like I had many options when I heard Mitsuki Bakugō shout from inside, with all the force of a mother reaching the end of her patience. A shiver ran through me: two different sets of angry-mother memories hit my mind at once.
So I did the sensible thing: I ran as if All For One himself were on my tail, trying to tidy up as fast as possible and get to the breakfast my "kind" mother had prepared.
As you can imagine, it was a pretty hectic and confusing day. After acclimating to the new memories and fighting the thoughts and doubts swirling in my head, I reached a conclusion. I was —magically— in the body of a young Katsuki Bakugō, a person of highly questionable beliefs and actions. Basically an idiot and a hypocrite of the highest order.
Great. Needless to say, I wasn't happy with the arrangement; sure, the powers were awesome, but not at the cost of everything I knew and loved. Also, there was the moral dilemma: I had "stolen" the body of a damn three-year-old —intentionally or not— and that was a shitty situation I wouldn't wish on anyone.
Even though I didn't particularly like Katsuki, the problem was that being in his body meant he was alive, and that, unintentionally, I might have committed a usurpation —or worse. A fucking mess.
I wanted to scream at the world and at whatever entity found it funny to shove me into this body without anyone's consent.
I let out another sigh of frustration. This is shit, I thought.
Then I heard someone shouting my name. I rolled my eyes in annoyance: the one calling was none other than a little green-haired kid. I looked at him, a bit irritated at being interrupted during my moment of relaxation.
—Izuku Midoriya.
That was the name of the nuisance approaching with a million-volt grin.
—"Kacchaaaan! Kacchaan! Katsuki!" —the broccoli-haired kid shouted cheerfully.
I sighed and replied sarcastically:
—That's my name, don't waste it, Izu.
The brat looked at me confused and then brushed it off.
—Kacchan, there's a new All Might figure at the shop, everyone else is there —Izuku said, waving his arms and pointing at a nearby store crowded with kids pressed to the display.
I rolled my eyes and nodded calmly.
—Well, what are you waiting for? Lead the way, Izu —I answered, half amused, half annoyed that they'd interrupted me under the tree.
The future heir of All Might squealed with joy and started running toward the shop.
I shook my head at Izuku's antics; he was certainly an energetic kid.
Well, it doesn't matter how I got here. Maybe I can do something good while I'm stuck here, I thought, watching Izuku run off. I clenched my fist. Even though I hadn't asked to be here, I would do everything I could to protect the happiness in this place. It was the least I could do for the original Katsuki Bakugō. I owed him that.
I promise: I won't give up, and I'll help you kick All For One's ass, I swore in my mind to the little green-haired figure.
