So theres a ruling regarding blackmail. Can we take it for granted that you can charge him in but he goes home bowed straight away? It might seem unimportant but theoretically I could charge him into play defending the first conflict, win the ring of water in the second conflict to ready him and then either defend my opponents second conflict or play cloud the mind on him to attack with him in my second conflict

If Shiba Peacemaker somehow ends up participating as an attacker (e.g. Blackmailed), he immediately goes home bowed.

Ps, meant to post this in rules forum, silly me!

From the rules reference (pg 12):

"If a character “cannot participate” in a conflict, that character cannot be declared as an attacker or defender for, move into, or be played into that conflict."

So you cannot play Charge to put Shiba Peacemaker into play as an attacker.
