What sort of tree doth be thee, that piques mine curiosi-tree? This comic's dialogue is based on lyrics from Hitachi's Tree, or What Tree Is This Tree?, a song that was common to hear on televisions in Japan from the late 70's—90's due to its prevalence in broadcasts associated with the Hitachi Group, which featured a sprawling monkey pod tree. The original line in this note appears to be a pun involving "tree" (ki) and "to wonder about [something]" (kininaru). The dialogue itself is informal, but the character Vivi is known to speak in a comically formal manner.

Since 'tis a tree whose name is unbeknownst to me...

...it will surely bloom flowers.
