Sincerity in Summer Flag

is the Noble Phantasm of Okita J Souji.
A festive punch-like version of the Noble Phantasm similar to the one Saber Okita Souji has.
For the purpose of exterminating the outlaw ronin rampaging the summer's sea, various misunderstood Shinsengumi soldiers are summoned.
The original Noble Phantasm that couldn't be used if not Saber-class, it's said that Assassin-class' Okita-san cannot use it either, it's the kind of Noble Phantasm that make you feels "if that's the case then when can you use it".
