Haunted by the past

What does one do when the past takes over their life? For one Azul Ashengrotto this happened in the very literal sense. After years of trying to erase and hide his past, all his work is undone when an accident occurs during Alchemy class that brings his past to the present, on display for all to see. An accident involving potions deages Azul back to his 10 year old self. His past self literally taking over his life. With a ten year old Azul with no memories of his teenage self, the leech twins are stuck with babysitting duty whilst others try and resolve this catastrophe but things aren't as easy as they thought it'd be and will things really be fine when Azul is reverted back to his teenage self after this ordeal?

TLDR: An accident in alchemy class deages Azul back to his ten year old self and the leech twins have to babysit but everything isn't perfect now nor when Azul is reverted back to his normal age.
