When playing Kyousuke, you play him first and foremost as a tank, saving Cast Off for opportune moments. Kyousuke should aim to gather as many stars as possible. Kyousuke should ideally have at least some healing in hand such as Pudding; however, Bonus panels should generally be prioritzed higher than Draw panels in order to gain a star lead. Due to his +2 DEF and high HP stat, Kyousuke can take Boss panels relatively safely if healthy, sometimes even being wise to choose Boss if it means avoiding a Drop panel. If Kyousuke is in dire need of a comeback or a good opportunity arises, he can use Cast Off in order to KO enemy units. However, the lowered DEF stat means Kyousuke is more prone to dying and having to make a comeback again, which may be difficult without another hyper due to reviving back in tank form.
Healing cards such as Dinner, Pudding, and Saki's Cookie can help Kyousuke survive longer and generally benefit him more than other characters, as his +2 DEF make his HP more valuable than characters with lower DEF.
As Kyousuke is not card reliant, Gift Exchange and Scrambled Eve can be used in order to blunt characters who rely on cards, especially ones that may use cards to gain a star lead over you such as Marie Poppo.
Pet Snacks is a very cheap event card that makes Encounter NPCs more threatening, which Kyousuke will often not mind due to a high DEF stat. However, it may hinder Kyousuke under the effect of Cast Off and generally doesn't harm the other players that much.
Oh My Friend can summon the Boss which other players are more likely to die to, however it's recommended you attempt to use it though Play of the Gods due to the high cost.
It's recommended to hold off on using Cast Off unless you feel it's needed to make a comeback, or there's a clear reason, such as the BattlefieldBattlefield Every 6 Chapters, all Bonus and Drop panels will become Encounter panels. This effect lasts for 3 Chapters. field event.
High EVD characters such as Sora are able to fight Kyousuke for relatively low risk; however, they are unlikely to deal more than 1 damage if fighting his tank form and still may lose a large amount of HP if they roll unluckily.
