Ollie, a maid in service to Angel's daily life, had a quite close relationship with him.
Mana, the Head Maid, was essentially the butler of Pat Manor, having served both brothers since their childhood. It wouldn't be an overstatement to call her an elder and family member.
When Angel did not see them in the underground wine cellar, he looked at Lyon with hopeful eyes, wishing for some good news.
However, Lyon's expression faltered, and with a complicated look, he shook his head with a wry smile.
After a while, Angel arrived outside the room of Mana, the Head Maid.
Although separated by a door, his spiritual power's probing feedback allowed him to clearly feel the situation inside the room.
