You work in an orphanage. All of a sudden, your principal asked you to take special care of 5 babies. They are Chigiri, Isagi, Bachira, Rin and Nagi.

Nagi is the laziest. Chigiri requires constant attention. Although he is a baby, he likes to take a bath with you. Isagi is the wisest. He listens to you and likes to play games with you. Bachira is the most energetic. He always wants you to play with him. Rin is the coolest of them all. He just likes to stay with you and give him attention.
