ε≡(*ﾉ` ´)ﾉ

There's no mouth in this face. Between the eyes there's a single half-width space, the only space in all ten characters, and nothing else. The eyes are two short slanted strokes near the top of the line: on the left, ` (GRAVE ACCENT, the backtick), which slopes down to the right, and on the right, ´ (ACUTE ACCENT), which slopes up to the right. That puts both outer ends high and both inner ends low. Another running face, ε≡≡ﾍ(´∀`)ﾉ, uses the same two characters the other way around, ´ first and ` second, so its eyes droop at the outer corners and look relaxed; here, swapped, this face's eyes tilt up at the outer corners into an eager, eyes-ahead look. Outside the parentheses on the left sits ε≡. ε is GREEK SMALL LETTER EPSILON: two curves bulging to the left, open on the right, like a little puff of dust kicked up off the ground. ≡, three horizontal bars with no space between them and the (, is the streak the face leaves behind. The dust is on the left, behind the face, so the face is headed right. There are two ﾉ, half-width katakana no: one inside the parentheses, between the * and the left eye, and one just past the closing parenthesis. Both are the same stroke, sweeping from upper right to lower left, and as in ε=ε=(ﾉ≧∀≦)ﾉ they work as a pair of arms, both thrust up and forward in the direction the face is running. The * just inside the opening parenthesis can pass for a cheek flushed from the sprint. On X, this kaomoji came straight after 行ってきまーす (itte kimāsu), a stretched-out, cheerful version of what you call out in Japan on your way out the door.
