Yu is spends an additional 2 minutes/day as a demon, which is an additional hour per 30-day month. Since 3 months pass in the time skip, Yu is already spending about 3 hours/day as a demon. In another 6 months (at a grand total of 9 months), Yu will spend 9 hours as a demon.

At a rate like that, Yu would take just under 12 months to spend half a day as a demon and will be a demon 24/7 after a grand total of just under 2 years. However, Mika says Yu will spend half of the day a demon after the first 9 months.

Why does this still make sense? Because no one ever said Yu started out his first day with only 2 minutes of being a demon. If Yu is spending 12 hours/day as a demon after only 9 months, then he must have started spending 3 hours/day as a demon the day after the battle at Nagoya.

I saw this question floating around elsewhere. Does this make sense?

180 minutes + (2 minutes x days) = the minutes Yu spends as a demon after Nagoya each day

Man, those kids must've freaked the hell out when Yu suddenly became a demon for 3 hours.

If it's like this, he may lose a few hours of time to being a demon should he transform into one voluntarily. If he abstains from that, he had a total of 21 months of humanity after Nagoya, which is now down to 18 in the current chapter.

He is spending about 6 hours a day as a demon right now.
