This collaboration resulted in scientific publication describing spectroscopic and photometric observations of 17 dwarf-nova superoutbursts obtained using the 3.8 m telescope Seimei at the Okayama Observatory of Kyoto University and through the Variable Star Network collaboration (VSNET). Our result suggests that a higher-inclination system shows a stronger emission line of He II 4686 Å, as well as larger-amplitude early superhumps.
