In Mashin Sentai Kiramager Ep. 9: This Is My Youthful Path of Karuta, a voice from afar suddenly calls out to her as she is jogging alongside Jewel and Tametomo! It was Sena’s own childhood friend, Muramura Makinobu!
It’s a touching reunion until she tells her that she is dropping out and then walks away! Sena is unusually affected by this given her appearance and is surprised by what just happened! Just then, another Jyamen Monster appears in the midst of the city!
Once Jewel and the others arrive on the scene they notice people struggling trying to remove giant cards from their foreheads! Sena is surprised to see the cards, suddenly exclaiming… “Wait! Is this… Makinobu’s curse?!” Attached to everyone’s foreheads is a Hyakkunin Isshu poem card ticket! And the name of the Jyamen Monster is… Hyakkunin Isshu Jyamen!
The Hyakkunin Isshu Tournament of Hell therefore involves having people complete the first phrases of poems by using the cards on their foreheads in the correct order! The Kirameigers are counting on Sena to win this challenge because of her previous karuta experience, and her unmatched speed and velocity!
