Miru and Kaku (ミル・カク) debut in the first episode of Hatoful Boyfriend: Holiday Star, "The Christmas Thieves Attack!".

They are never seen without the other, and are mischievous with a great love of Christmas. They like to disturb Shuu.

In the Holiday Star demo, we see them in the infirmary with Yuuya, wishing Merry Christmas. Later, they start the cheering for the Popocures. Shuu was overseas during the whole story.

The main thing they seem to say is "Merry Christmas" (メリクリ).

Early Life

They're lab accidents from the St. Pigeonation's bio lab Ryuuji and Shuu worked in.

They were going to be killed when Ryuuji saved them and brought to them a great love of celebrations and Christmas.

Hatoful Boyfriend: Holiday Star

"The Christmas Thieves Attack!"

After an unusual bout of sentimentality, Shuu accepted them into his care after they were discovered robbing Christmas trees from all over town near Christmas time. They ended up transforming the infirmary into something unrecognisably festive.
