Based on @koyuki-tan‘s “Peace Sign.”
Higmaru thinks it’s adorable. He wants to dress Oscar up in a suit and tie. He may be planning on asking Brooke out to dinner using a cute Oscar.
Saiko disagrees. She doesn’t trust Hige to actually ask her. So, her plan is to kidnap Oscar, put him in a metal bikini a la Leia, and send Brooke ransom notes.
The ransom would be going out with Higemaru. When Hige protests that it’s a bit too manipulative to start a relationship, Saiko concedes…
And places notes leading Brooke to find Oscar in Higemaru’s room anyways.
