While in BiS, Wacky and Pour Lui both took part in a 100km marathon over the course of 24 hours, running from Yamanashi to Shibuya where they had a live performance due afterwards. Both of them failed to complete the run. Wacky managed to run 86km before being made to give up as she ran out of time and wouldn’t have made it to the live show. The music video for [hitoribochi] documented these events.
Unfortunately, from the marathon, she aggravated a prior ankle condition that she had from before joining BiS. After much deliberation with BiS management, they decided she would leave the group.
She said that she wishes to focus on her health and also her studies at university.
