Safety first

I accepted his offer. Skyler took me and Shin Chan to a large terrace on top a tall building. I saw a theatre ,a old one which haven't been used for a long time. This world is surely a peculiar one .He told me that I could stay here for now . He gave me a cellphone so I could contact him .He soon took his leave and left me and Shin Chan alone. Shin Chan haven't woke up by now .I quickly opened up my book ,I need to send Shin Chan back quickly before anything else pops up. How will I do that ? thats when some words appeared in front of me ,the language was surely different ,how can I read it? I checked my bag for anything which seems helpful. Ah I found the handkerchief from before ,I really have no idea how to use it ,should I wrap it around my wrist ? I wrapped it up ,no it didn't work .I opened the book and to my surprise a page had appeared from nowhere. I read it ...

" item: Handkerchief

speciality: high eyesight

This item can be used during combat , during darkness and can also be used to read ,if used in the right way."

Right way? come on ,how should I use it ? umm a bandana ,lets check it. I tied my hairs in a cute manner with the handkerchief. Then adjusted my view on the words and I can finally read it , it said something which seems completely useless for me.

" item: hyacinth

speciality: Kill

The stem of the hyacinth grows long and sharp when danger is sensed. Be careful since the point is highly poisonous."

Umm this doesn't solve my query on how should I send Shin Chan back. I don't want to face his questions and his eyes which will surely see me guilty. It's already morning and I haven't heard anything from Skyler and even Shin Chan did not woke up. I slept the whole morning since I couldn't sleep in the night.
