Iruma deserves the world, imagine having to re live those awful years with his so called family..
True, he's still too young and small yet he's carrying too much burden and the living world isn't good for him anymore, he has no one there, while un the underworld he has family and friends and lot of precious relationships and memories! He deserves it!!
Fr, he's finally voicing his opinions and being so happy with his grandpa, opera and his friends. As much as I would like to see him explore the human realm with his friends, I prefer he stays safely in the underworld instead until he's definitely ready
Saying Iruma walk away while holding his grandpa's hand hits different, it made me realize
"He's just a kid! So much happened we forget he was only a 15 years old boy!!! He's carrying too much?"
