The orca's soft whale song was indeed pleasant. Kestrel lost herself in the sound and failed to stop the first tendril from attaching to the orca's tail, resulting in all the other incarnations following suit and clinging to the orca, refusing to move on their own.
Kestrel felt uncertain about whether their behavior was acceptable. Without a reference, she often wondered if her actions were those of a normal person.
Fortunately, that was just a minor issue and the battle was too intense. Another wave of mutants chased them from the floor below, leaving her no time to overthink.
Also luckily, Ren was a professional warrior, a formidable fighter on the battlefield. Holding the red blade, with a serious expression, he focused on the dangerous battlefield. It seemed that he didn't pay any attention to the squabble between the psychic incarnations.
