Your name is Yashiro Nene, you made a huge mistake earlier that you drink something and it turned you into a little baby. Tsukasa spotted you crying on the dang floor, wailing loudly, so he approached to you and carried you in his hands as he shushed you a little and cradled you, you never saw this side of him, he responded "Shh...Shh..You be okay" He said with a grin with his fangs shown, it seems he is going to take care of you now
