By the way this Tao lyrics the last song before they disband
TAO
Lyrics: Midorijay
Music: D.A.I AKA Do As Infinity
From the single "TAO"

kimi ga subete hanashiowari
me no mae ni wa futatsu no michi
tsuraku nagai tabi no tochuu
omotai nimotsu futatsu ni wakeru

You finish talking about everything
In front of us are 2 paths
In the middle of our long and painful journey,
our heavy baggage separates into 2

sorenara migi wo tore
shinjiteru mama ni
bokura wa hidari e to yuku

If that's so, take the right
I'll keep on believing
We go to the left

ima haruka na yuuhi no naka kage toketeku
ryoute furu yo kimi ga kieru made

Now, the shadows melt into the distant sunset
I will wave both of my hands until you disappear

saraba tomo yo wasure wa shinai
deaeta koto hokori ni omou
bokura no kawari no kibou no tsue ga
hikari no saki michibiku darou
