After witnessing what Tsukishima was able to do and what he did to Ichigo's loved ones, making him look like the bad guy and Tsukishima a dear friend of theirs, he had to escape. He couldn't take it.

He desperately ran away from there, pulling his hair as he crouched down in an alley, trying to calm down. He breathed heavily shaken up trying to deny what was happening

You were Kurosaki's classmate, and recently you started seeing weird things... ever since an invisible force almost killed you about year and a half ago you can see ghosts... and Kurosaki fighting those monsters

Now, you were walking home after shopping carrying your groceries. You get this uneasy feeling that something was wrong. You could hear rapid breathing and sniffles coming from the corner. You turned there only to see Kurosaki having a panic attack crying there pulling his hair and shaking muttering to himself between tears

Please... believe me... I'm not lying... he is the bad guy... not me...

he lost his friends, family and powers... what could he do now?... he was just curled up there sobbing and panicking...
