Orihime wouldn't shut up one day. She missed Ichigo, or the strawberry too much. None of the arrancars could sleep and they all yelled at Ulquiorra which made him angry. At 2 AM when Orihime was having a fit, Ulquiorra walked in and told her to shut up or he'll shove a pillow down her throat. Orihime thought he was really mean so she slapped him
Ulquiorra got angrier with her and then beat her with Nnoitra.
Nnoitra got mad and killed Orihime.
Ichigo noticed he was too late to save his love so he commited soulreapersuicide in front of Rukia and Renji.
He swore he'd kill Ulquiorra with his godmood hollowmask.
Even though hes dead, with Orihime now.
The soul society fell apart.
Except for Hitsu cuz hes cool.
