This is what I have deciphered on my own, although it still makes no sense to me.
I think it is combination of both Hiragana alphabet and Kanji. . I am positive it is Hiragana for RA, RU and SU. I think the O is a clever design using the strokes for SU combined with the right half for O. The strokes for SU are the same as the left half of O. I believe the last shape on the left is a Kanji, as there is no Hiragana letter even close to it.
