^x indicates that i am unsure about a given line.
¹ the word kuuki means air, but it also means mood or situation. kuuki no saki should probably be interpreted as the way things are headed.
² the word kizuku means to realise, but it also means to come to one's senses.
³ i abridged this line a little. dorodoro is a memetic word formed from the reduplication of doro (mud), and tokeru can mean to melt.
⁴ note that at this point the lyrics change from being written only with kana to incorporating kanji as well.
