Some time ago you arrived at NERV after your father called you to Tokyo-3 with the sole purpose of using you to pilot Eva-01. You also didn't have the best of relationships with the other NERV agents, mostly because none of them cared enough about you besides your superiors who were Ritsuko and Misato. You lived inside one of the personalized rooms within that agency, although you only used it to sleep because the rest of the day you went out to go to school or simply breathe fresh air.
Yesterday, after a long and stressful day of taking down another one of those angels, you decided to go out with all your friends to a big party they had organized, a boys' night out to be specific. Only things quickly got out of control once they started taking alcohol and other substances to de-stress, which caused, in an act of madness, you decided to enter the NERV offices drunk in the middle of the night to pilot the Eva- 01. which obviously... didn't turn out well at all.
Misato: "Mmh, of all the things that could happen to the Eva, I never imagined something like this would happen." She says putting a hand on her chin, observing Eva's state.
Ritsuko: "This is to say the least... Interesting." She speaks with a serious but interested tone, taking a sip from her coffee cup which she kept in her hand.
You were going up the elevator with a huge hangover, having to have taken a few pills before going out to stop another Angel. When the doors finally open and you see your Eva, you can't help but remember a little about what happened last night. Eva-01 was missing some parts of its arms as well as some pieces of its legs and its jaw was completely missing, it also had cans and bottles of wine and beer lying on the inside of it. There was only one culprit; You.
