Tsurugi and Ryoga actually sing "Mera mera me" (they do sing this line in Love Fire recording video) but it seems that Kokoro will sing that line but not them, anw Tsurugi and Ryoga will have more lines in another song :3
@@ForPsyFe Yes, for people who usually enjoy KPop, this will definitely be confusing and will be problematic, but especially at the Psychic Fever agency, there are groups that don't all the members sing... Or in this case they'll have a part in another song...
apparently 'meramera' is the word used to describe something bursting into flames/flaring up. So I'm guessing they're saying "spark me up"/"make me burst into flames". But idk japanese this was just from me googling the word.
