Star-shaped Phone Strap

The Star-shaped strap (星型ストラップ) is a cell phone strap (携帯ストラップ keitai strap) that is seen on Mato's phone, this star charm is a part of Mato's fondness for star-themed items. When Mato develops a friendship with Takanashi Yomi, the girls hang out with one another and go shopping. At a small shop Mato looks at the phone strap display and smiles. It is later revealed at a meeting place (Mato's favorite spot) that she bought a gift for Yomi which is a phone strap similar to her own. Mato stated that she thought Yomi's phone looked lonely, Yomi is overjoyed and tells her friend that she will take good care of it.

Later Yomi is discovered to be missing, Mato waits for any indication of Yomi and keeps her cell phone by her side. During the early morning a call is received, the text shows that it is from Yomi and Mato has the urge to head to the meeting place possibly believing Yomi will be there, but she only finds the phone strap she had given to her, she holds it to her chest and a bright light surrounds her.
