It is ironic how via making Chika in "killer mode" she "saved" herself from the gangrape... @Zael small inverse mistake. You can just read in the Sleepy Panda site, it is released.
On one hand, it probably would've been smarter for ONIICHAN not to blow his disguise and for Rein to act like nothing was wrong. On the other hand I really doubt she'd be able to pull that off, and seeing Dr. Feelgood take a knee to the face is great.
