Whaaaaaat? Gotta be arson. Someone has it out for him. The obvious culprit is the bald guy (more likely a proxy), but that may be too obvious for fiction. I’m curious about the conversation between him and an employee at the end of last chapter. I read through it again and nothing sticks out to me as being incriminating or suggesting foreshadowing. I would be curious to hear the an interpretation of the conversation by a high-level or native Japanese speaker. I wonder if it could be a severe case of sub-context and reading between the lines. Or it could be a big red herring, what do I know? That conversation was the first thing I thought of when I saw the fire though.
Just to be clear: None of the above is meant to impugn the translators of this scanlation. I apologize if anything came off as questioning your abilities, that is not my intent. Thanks for continuing to work on this, I really enjoy it.
