[sometime after the dust settles
here, Shizuru'll get down to some damage control. She may not have the authority to force ridiculous explanations down people's throats, but what she does have is meter-breaking powers of bullshittery for covering up troublesome episodes. The following message is written in clear, strong script]
This is regarding the explosion which occurred some time ago on the sixth floor. It was an accident; the chemistry experiment I left in my friend's room had an [pause] adverse reaction to the steam from her bath. The results had an unexpected hallucinogenic effect, and made her imagine someone was in there with her.
I am looking into it, but I urge whoever had been there to get themselves examined by the professionals at the clinic.
Apologies for any inconvenience caused.
