Label on the substance bag in the tv show maniac In S01E03 of maniac we can see this bag: ![enter image description here]( What is the symbol between and ? Is it supposed to be 1, like for version 1? If so shouldn't it go after the ?

It is not a number 1, as you might think. It is a valid katakana which is a small : .

The word in question is then:

>

These kind of small kana are used in conjunction with the previous kana in order to modify the sound. In this case, where the kana is and gives a 'te' sound, adding the small kana in front to make gives the 'ti' sound that normally can't be expressed in the standard kana range. Recall that the normal sound for the 'i' range in the row gives us or 'chi'.

So, now that you know this, what word is this?
