Oh dear... This is getting bad.. Ichirou was a part of our Yakuza Family. He was not part of the Mutineers. So, we might have really lost a blocker.
Apart from Yasuko's accidental death, only Tadao was murdered by the very Ninja who wield 2 katanas. I am extremely bothered by this 2 scenes... The outfit for the 2 vigilantes are obviously different and why is there only one killing? It makes me wonder if those killings can only be used on alternate days on either sides? I am making a bold assumption and often enough, I am not sure if pictorial clues might help.
I hope to consolidate my thoughts on this killing issues for discussion, and ultimately in latter days, this might become clearer. I am also quite certain and confident that certain patterns can be established through pictorial aspects.
As you can see in Night 1, that was definitely a Ninja donning his/her Black or Green Ninja grab that had killed our young Lloyd! While, in Night 2, Tako was killed by a Ninja who had donned another Ninja grab design, which could be ranging from white, red or grey. My gut feeling tells me that the Night 1 killing is done by the Mutineers. For some odd reason, this did not happen in Night 2 and it was obviously killed by another different person. I don't have firm grounds why only one killing took place and whether if it's by choice or by the settings of the environment.
One more interesting to note, Llyod's teddy bear is still around and I can't help but to think that there are hints behind these. Maybe I ramble too much but I hope I can at least piece some of the coincidences together.
