after aiden became Eri's new dad, which is what the papers that Kiriya pulled out turned out to be adoption papers for aiden to sign, which he did anyway

now we see Aiden tucking eri in as she is sleeping on aiden's bed, then he got a text from Octavia and as he read what her text said, he grew a shocked & fearful expression on his face and as he was about to scream, he sees eri sleeping and he didn't want to wake her up from her nap, so he quietly left his dorm room

(in front of UNION)

Verosika: oh come on, can you just let us in, you bucket of bolts!!!

she yelled at the ATLAS KNIGHT 1000, which spoke in an automated voice

AK 1000: sorry, i'm afraid i can't let you in.

it said

Blitz: OH YEAH, WHY NOT!!??

he yelled as he pulled out his flintlocke pistol and aimed it at the robot, which aimed it's rifle at blitz's face

AK 1000: because the students are about to start something relating to the student known as Aiden October....and that you are causing a scene, look behind you.

it said, making the demon/demoness guests turn around and see random UNION students stare at them in shock, even team CRDL are there as well

Octavia: oh.

Cardin: who are you freaks?

he said, making them offended and angered at hearing what he said, but before Vaggie walked up and slapped him...

Aiden: guys, what are you doing here?

he said, making octavia & the others turn around and see aiden standing there, and making the students puzzled

female student 1: wait, you know them, Aiden?!

she asked in shock as the students and team CRDL stare at him

Aiden: well, yeah, but it's kind of a long story. but short version, i met them before UNION ACADEMY Showed up here on my earth.

he said

male faunas student 1: well can you tell us the long version in the ampitheatre? becaus-

he was then interrupted when the All Might spoke through the intercom

All Might: Aiden October, you and the guests are needed in the union ampitheatre, please come.

he said as aiden and the others (hazbin crew, octavia & stolas, Verosika & her crew, even IMP) wondered why he's needed in the ampitheatre, so they walked inside

(at the ampitheatre)

we see aiden and the gang walk towards the ampitheatre doors and see Yang and Blake standing in front of the doors with sympathetic faces when they looked at aiden

Aiden: is there something wrong, Blake & Yang? why am i needed in here

he asked as yang sighed

Yang: because....

she trailed off as she opened the door, revealing that all the UNION Students and staff were stitting in chairs, lined up in a curve, making aiden and the gang (hazbin crew, octavia & stolas, Verosika & her crew, even IMP) realize what this is

Nora: It's an intervention.

she said, like HUE from FINAL SPACE Season 2, making aiden sit down on his chair and the gang sit next to him

Aiden: why am i having an intervention? i don't have any problems right now.

Lucy: you may not have any now, but we now know that you had a MAJOR problem for over a decade before you came here.

she said as Erza, the fairy tail girls, team RWBY, the females in Class 1A and asuka's team nod in agreement and sorrow

Aiden: ......(sigh) you googled my name, didn't you?

UNION Students: yeah, we did.

they said in unison

Erza: but we we're a little betrayed by the staff and master makarov that they already knew about this and didn't tell all of us about your past.

Lisanna: but it was for a good reason on why they didn't tell us.

they said in sadness

Ochako: aiden, you had a really dark and depressing past.

she said as deku patted her on the back and aiden lowered his head at thinking about it

Aiden: i know. and i regretted doing what i did a week before i came to UNION and i'm tired of keeping this a secret from you all, so i'm gonna come right out and say everything.

he said as he breathed in and spoke the truth

(french voice: later)

after aiden said the truth on what happened before he came to UNION, the students were shocked, horrified and saddened at hearing what aiden told them, except the staff because they also knew about this, even the parts where the guests are demons that aiden befriended and were nothing like what they expected to be

Bakugo: (wide eyes) so you're telling that you actually tried to kill your own sister to get revenge on what she did when you were 7?

Todoroki: but you decided to let her live after she told everyone in hell, even you, that she's pregnant?

they asked in shock, making aiden nod

Aiden: yeah, after she told us about her pregnancy, i decided to abandon my revenge and just move on to have a fresh start, which the 3rd reason on why i came to beacon, i was about to say it on day 1 until Dr. Oobleck ran into our history class like the flash, roadrunner or sonic.....no offense.

Dr. Oobleck: none taken, i get it all the time ever since we showed up.

he said as aiden nodded to oobleck in understanding

Aiden: also, now that i told all of you the truth, you guys must hate me for all the stuff i did to get my old revenge.

he said as he lowered his head in sorrow and regret, along with the hazbin crew, octavia & stolas, Verosika & her crew, and IMP, then suddenly ruby got up from her seat and, well, straight up KISSED AIDEN ON HIS LIPS!!!!!!!

everyone (except staff):
