Izuku, Eri and Ochako finds themselves on the motorcycle, parked in front of a train station.

"Wow, Papa became a detective!"

Izuku looked down to see that he is wearing a detective's stereotypical outfit consisting of a tan trench coat over a white shirt with black tie, and a pair of matching jeans.

"I do, don't I...?" Izuku nervously laughed.

He felt something in the coat's pocket and takes it out.

"A train ticket? But it looked unusual." Ochako noted.

"Are we going on a vacation, Papa?"

"It seems so, Eri. A vacation through time!"

Eri then cheered. A vacation, on some other world.

"Do you think we're finding the instant costume user of this world soon?"

"Perhaps, Uraraka. Perh--"

It was then when something went inside Izuku's body like a ghost possessing a human.

"Deku-Kun?"

Sand begins to pour out to Izuku's feet, scaring Uraraka while Eri just played with the sand.

"Yoshaaa!!! I've found you!"

Izuku then went over to some letterman, and beat the living hell out of him.

"W... What's your problem!?"

"I can see that you're possessed! Leave this body immediately!"

The letterman then laughed.

"Your eyes... I shouldn't have underestimated them!"

Sand begins to pour out from the letterman's body, and from within, a humanoid cockroach like creature came out, disgusting both Ochako and Eri.

"You really are a dunce, revealing yourself wide open like this! Henshin!"

The possessed Izuku then flashed the ticket to a belt that materializes around his waist.

"SWORD FORM"

A silver masked armor with a bodysuit underneath then formed, before Mina's hair formed on Izuku's head and another set of colored armor plating completed the set.

"Watashi... Ga Kita!"

"So All Might also existed in this world... As Mina?" Ochako sweat dropped.

The creature tries to attack Mina, only for her to sidestep and do a backhand punch to the back of his head.

The creature tries to attack again, but Mina pulls out a sword from her hip, and slashed the creature in the gut causing him to drop down as he passed.

Before he recovered, Mina flashed the card one more time to the belt.

"ULTRA CHARGE"

The sword's blade then flew to the air detaching itself from it's guard. A rope of acid connected the guard to the flying blade.

"Behold, my Hissatsu Attack!"

Mina then swung the blade left and right, slashing the creature before lifting the blade up high and dropping it down as it is dripping with acid.

The creature is cut in half, and exploded in a big explosion.

Mina then returned into being Izuku, and tries to walk away.

"Papa, where are you going!?"

"Shut yer yap, brat! I'm borrowing your dad for a bit--"

Ochako karate chopped him in the back, causing Mina to float out of Izuku's body as soon as he's knocked.

"You round faced whore! What did you think you are doing!?"

"You shouldn't borrow his body without his permission!" Ochako replied.

"You do have a point, though. Who am I supposed to use as a vessel though?"

"You can't have your own body? Like that creature just now?"

"No, she couldn't Ura-Chan."

Izumi walks out from a warp gate, and explained "This world's Ashido Mina is an imagin. They live like spirits, able to possess people, but Ashido here is a different case where she is more to heroics than destruction."

"So, who are we going to use as a vessel for her?"

"Hold on a moment, Onee-Chan does have a card that would fit... Not this..." Izumi begins to check out her card book.

She stopped when she reaches Toru's card. She then summoned her using the card by inserting it into the card reader attached to the gun barrel.

"SUMMON CARD - HAGAKURE"

She shoots out and a bunch of silhouettes danced around before fusing into one. It's Hagakure in her casual wear.

"Now for a temporary amount of time, use her body."

Izumi pushes the summoned Toru to Mina, who instantly possessed her. It was then when Mina's form appeared, wearing Hagakure's clothes.

"Now that's the Ashido I know!" Ochako noted.

"But... I still don't know what I looked like. I couldn't see myself in a mirror because of this girl's invisible properties."

"There has to be a way though." Izumi puts a finger to the bottom of her chin, thinking.

"Ah, could it be that the Final Form card for Ashido might be..."

It was then when they are approached by another creature, this time it's a black humanoid wolf coming out of a policeman's body.

"I've found you at last! The Imagin who killed her own race one by one!"
