 * "Burger World": The Sharks hold everyone hostage at the eponymous eatery and threaten to kill her if Shohei screws up. What happens? Shohei gets Hikari II to help, and with its newly-grown vines, pwns Orin's flunkies, snatches his katana out of his hand, and threatens him by chopping the table the Sharks ate at in half, which causes the gang to flee.
 * Hikari  in "Christmas".
 * "Cherry Blossom Birthday":
 * The ending of the final chapter tops all of those.
