create alias irina_kushu -> irina_kush
create alias irina_kushu_(christmas_costume) -> irina_kush_(christmas_costume)
create alias ayano_rika's_ex -> konoka_(madoka_magica)
Kushu's name is officially romanized as Kush in Magia Exedra's global version and Ayano Rika's ex randomly got a name in Exedra as well so I figure our tags should get updated accordingly.
