Not sure if I right... On the bottom left of JMSDF Kaga is a Tosa-class battleship (dunno about the name of the ship) which the constructions is canceled because Washington Naval Treaty and as the result they convert that battleship into a aircraft carrier Kaga.

P.S: adding akagi tags

Question, why tagged Kantai Collection when I don't see any reference to it. Removing it as well as replacing Akagi(KC) with Akagi(CV)

There isn't, changing the Kaga tag too.
Though interestingly the JMSDF Kaga only has a character tag.

I thinked hard when i look at this pics without looking the tags

The left one : Tosa-class battleship, Kaga
the right one : Converted to Aircraft Carrier, Kaga
The front one : Izumo-class helicopter destroyer, Kaga

But the behind one, i still think its a ship with "Kaga" name before i actually realized that is Akagi

Because it's tagged with Kantai Collection's tag on Pixiv? Would that be a good engouh reason?

Not a good excuse.

Really, if you look at Kantai_Collection Original you find really messed up tags there. For example, how exactly do you justify mikasa_(kantai_collection) tag? She's not even a planned drop (yet).

EDIT: Never mind, I should really put attention to the tag descriptions. Though, mikasa_(character) or something like that would fit better.
