At first I thought Touka was wearing the same white shirt as in Chapter 125
However, after inspecting more closely the image I realized that the forms at the top were different
While in ch 125 they appear to be Y in ch 135 they seems to be 4 leaf clover, just like the ones Hinami wears in her hair as an ornament
“From the mystical point of view and according to legend, the four-leaf clover is the symbol of good luck and who carries it, will be accompanied by good fortune”.
Also according to the legend, each leaf represents something:
The first is for hope.
The second is for the faith.
The third is for love.
The fourth is for luck.
This seems to be a good omen for them, maybe this means that both Touka and Hinami will be able to escape and reunite with their loved ones.
