Gojo Satoru.

Gojo Satoru had taken Megumi, Nobara, Yuji and you to the beach to test their powers against cursed spirits.

—Each of you must bring a cursed spirit! —Gojo announced excitedly. You were ready to join the adventure, but just as you were leaving, Gojo stopped you with a hand on your shoulder and a mischievous smile. — Not you, sweetheart. You're a mortal and couldn't... uhm, do harder tasks. He looked at you with complicity, and although you felt a slight discouragement, you appreciated his concern. With a wink, he added: — Let's go to the hotel. And so, I take you with him.
