Actually, just vote Shinya.
The pattern of votes. The mafians have an order of which they lynch.
Round 1: BZ1 AND Delpen
Round 2: rrhunt (not caught) OR Ledgend (lets say Ledgend did this one)
Round 3: Shinya or Self Destruct (assuming Shinya)
Round 4: rrhunt (rrhunt was killed),
Round 5: Ledgend or.... Shinya (Lets assume it was Shinya) (Ledgend was killed)
Round 6: Rue OR Delpen (Hmm...)
Round 7: Rue OR Shinya (Shinya appears)
So the loop is this:
BZ1
Ledgend
Shinya
rrhunt
Newcomer
Round 1: BZ1, Ledgend, Shinya, rrhunt, Newcomer
Round 2: Ledgend, Shinya, rrhunt, New
Round 3: Shinya, rrhunt, New, Ledgend,
Round 4: rrhunt, New, Ledgend, Shinya
Round 5: New, Ledgend, Shinya
Round 6: New, Shinya
Round 7: Shinya New
So the newcomer would have killed in Round 5.
We have 3 options in Round 5 of who were/was mafian.
Ledgend - Killed. Confirmed Mafian. Was he Original Mafian or newcomer?
Delpen - Was in round 1. Could have been first mafian to kill, had a double scene.
Shinya - Already proven mafian. Most likely original mafian.
Ledgend was likely the newcomer.
Shinya is likely original Mafia.
Meaning Delpen is innocent.
HOWEVER
Does this really prove Delpen is innocent?
With Ledgend being the newcomer, it changes the whole list:
Round 1: BZ1, rrhunt, Shinya, Mereel, Ledgend
Round 2: rrhunt, Shinya, Mereel, Ledgend
Round 3: Shinya, Mereel, Ledgend, rrhunt
Round 4: Mereel, Ledgend, Shinya
Round 5: Ledgend, Shinya, Mereel
Round 6: Shinya, Mereel,
Round 7: Mereel, Shinya
THIS is the likeliest option.
Mereel shows up Scene 6, NO MAFIAN FOUND.
Mereel AND Shinya show up Scene 7.
IMO, Vote Shinya, Then if Mereel shows up next scene... you may have your answer. Either way... I believe Delpen is innocent.
For the last two scenes, I don't think it really mattered who chose. But the mafians kill off confirmed pro town each time. Which means that Remnant is next to die.
EDIT: Now whether this is accurate or not... that remains to be seen.
