Also in the sector of charm-strange physics the CQM does not seem to describe properly all spectrum, despite of theoretical expectations. These new forms of quark bounds clearly show that mesons and baryons are not the only possibilities to be considered. We shortly report in this paper selected recent results on searching for such states at Belle, with the perspectives in the hadron physics program at the Belle II experiment. 000000906 6531_ $$aExotics 000000906 8560_ $$felisabetta.prencipe@desy.de 000000906 8564_ $$uhttps://docs.belle2.org/record/906/files/BELLE2-CONF-PROC-2018-010.pdf 000000906 8564_ $$uhttps://docs.belle2.org/record/906/files/BELLE2-CONF-PROC-2018-010.gif?subformat=icon$$xicon 000000906 8564_ $$uhttps://docs.belle2.org/record/906/files/BELLE2-CONF-PROC-2018-010.gif?subformat=icon-700$$xicon-700
