I could have her join the kendo club so she spends less time at home or something... :D

That works or if you dont want her being an active member right away, she could be a ghost member who rarely, if ever, shows up. Maybe spending time elsewhere within the school, using the fact she joined the kendo club as an excuse and sticking around the school to make it seem like she's actually at it. And until you feel its the right moment for your character to actually attend kendo practice, you can come up with something that leaves her no choice but to attend. Like say one of her family comes to school or something. idk
