The Devil is a Part-Timer manga volume 7 features story by Satoshi Wagahara and art by Akio Hiiragi.

In The Devil is a Part-Timer! 7, Maou (the Devil King) has a suspicion about the mysterious child Alas Ramus, a wee lass who he and Emi (the Hero) have wound up parenting. During a supremely awkward "family outing" to the amusement park, Emi gets Maou to tell her the truth about their little girl. But when a chorus of angels shows up to settle an old score, Maou's revelation may not matter!
