So... we're just going to pretend that the old man dressed in black didn't tell Utako to die????
Why was that convenience store clerk suddenly pondering the afterlife?
Why was Daikichi completely unfazed by witnessing a dead body?
Why was Daikichi able to see and touch Kana from the very first moment of being in the apartment?
Why were Kana's breasts getting bigger?
Why did the circumstances of Kana's death keep changing between stabbing herself and cutting her titties off?
Why did the man with no name at the Grave for Lost Souls have an injured arm?
Why did Daikichi never go back to the Grave for Lost Souls?
How was he always able to afford beer despite being unemployed for nearly 3 months?
And most importantly: WHY THE FUCK DID THEY HAVE TO MAKE ME CRY WITH THE GHOST PUPPY?!?!?!?!?!?!?!!?!!?
Old man dressed in black, typical hater but instead in Twitter, it's real life.
Dunno, probably having occultist fanatic around and some kind of actual proof makes people wonder how it is afterwards. She was sick in last chapter and came back to work regardless, in illness such things may cross your mind.
Daikichi unfazed by suicide, well he is living with one victim of it, it's not his first rodeo, but nevertheless was fazed as he didn't saw a ghost. Maybe the person had finished it's business to not feel regret, but still felt there's no place for in this world, in opposite to Kana and moved on to the afterlife.
Daikichi full interaction with Kana, they somehow connect, maybe they were destined to meet but her untimely death didn't stop it.
Bigger breasts, common misinformation about "touch breast=bigger size" or fact she is a ghost and can manipulate her appearance as see fit, as she can "grow" legs, extend arm and whatnot.
Circumstances of Kana death known to public were a really short newspaper report, it skips a lot of details like severity of body because it's not pleasant.
Occult magazine probably got hands on police or coroner report through bribery and skipping that part would be a continuity error.
Person tending the Grave for Lost Souls had an injured arm probably before it's only his work, if he had help, Daikichi wouldn't help him, no story, etc.
Why didn't je came back? No reason, the body was gone after 10 years, probably cremated or withered away so even tending it and praying even served no purpose as he gave respect to Kana all the time.
How he had money for 3 months? Most likely not American living on credit and having savings like a reasonable human being. Heck, could go full hermit and probably live in an abandoned house for a year now or more. Also, beer is cheap and filling as it's high in calories.
Puppy scene, to show if something die with regrets left behind, dogo couldn't let go of it's master till last farewell during the burial ceremony, which Kana didn't had technically as nobody close to her said goodbye. Don't worry, doggo will be waiting in fire hydrant heaven for it's master.
Also, as mentioned earlier to show Kana can see ghosts but hadn't have a chance to see one as usually they pass on by to the afterlife.
