Canon
They met for the first time in Lero ro's test on the second floor, which Serena and Shibisu managed to get through the Shinsu barrier where intially they already failed, but they managed to get through the barrier thanks to their sheer force of will. After passing the test we can see them celebrating clashing the hands between them two.

In the Crown game, we can see that both characters are in separated groups (Serena teamming up with Lauroe and Ho, while Shibisu teamming with Anaak and Hatz), but they could finally meet again in the second round of the game which one her team and Serena fought against Ship Leesoo alongside Ho.

In the Last Examination, we can presence Serena and everyone else (Shibisu too) visited Ho's funeral given to him. Later, we can see she already failed the Position Test, but even so, she managed to present at the party with Shibisu and all the other Regulars.

It's also showed too how Serena was leaving the Inner Tower and she said My life it's nothing but regrets and then she gave Shibisu her knife as a parting gift and then she leaves the Tower with a Don't you dare to die, Shibisu along with a smile to him.
