The O-Ni is a Japanese tier 7 heavy tank.
A further development of the O-I with improved anti-tank guns. The military command's plan was to improve the earlier models and achieve a higher level of armor protection on the vehicle. Existed only in blueprints. No finished prototypes were built and the vehicle never saw action.
Also known as "Oni-chan" (thanks to anime influence), The O-Ni represents a fairly significant change in attributes from the previous O-I from its design layout being taller, bigger and having tougher armor in the front all while having an added perk of being quite a lot lighter (100 tons compared to 150 tons O-I).
It has to contend with the added weak points of its frontal turrets and the corner cheeks due to its armor layout. This makes angling and side-scrapping much less effective compared to its predecessor. It also sports some of the worst camo values in the game and speed in which, combined with its massive size, make it an easy target for SPG fire and spotters. On the other hand, its frontal armor and guns remain impressive for its tier and also has the largest HP pool out of any Tier VII. It has a very distinctive look that resembles some sort of battleship, in particular from the front.
While it still retains its predecessor's 15cm derp cannon, the O-Ni has a slightly improved reloading time. The O-Ni also gains the ability to use the improved experimental 10cm gun which can easily devastate most tanks you will face in battle with its faster reload. The O-Ni is best played as a second-line support tank that provides fire support while surrounded with cover as to protect its huge weak side & rear armor.
The O-Ni leads to the O-Ho.

Player Opinion
Pros and Cons
Pros:
- Very durable and tough frontal armor and has the highest HP pool in its tier (1550).
- Choice of two viable guns; the 15cm derp carried from O-I with huge alpha damage or 10cm gun with higher penetration, DPM & ROF.
- Strong, tall main turret paired with great gun depression (-9) is decent for hull down, can easily shoot over covers and allied tanks.
- Surprisingly good engine power to weight ratio results in good acceleration & decent speed for its size (23 km/h avg), great for ramming.
- Great view range for its tier.
- Easy stock grind as most modules except the improved exp 10cm and tracks are carried over from O-I, doesn't have additional turret to research and doesn't need tracks to equip modules apart from improved exp 10cm.
Cons:
- The tallest tank in the game, resulting in the absolute worst camouflage value out of all tanks in the entire game, it is easily spotted and difficult to hide and maneuver due to its massive size.
- An artillery and gold magnet. It also attracts one of the most attention from the enemy team.
- Mobility is hampered by low speed limit, agility is also pathetic.
- Large flat armor all-round. Very weak and huge side armor combined with mini-turrets & cheek weakspots makes armor unreliable, especially when angled.
- 15cm gun still has poor accuracy, aim time, and DPM. Both 10cm's gun accuracy is subpar.
- Ammo rack is large and easily damaged.
Performance
The O-Ni is the next step towards the end of the Japanese Heavy tank Line. Having the most hit points at tier 7 (1550 hit points), it can take a lot of punishment and still fight back. The choice of two top guns is the same as it's predecessor, the O-I, with a small increase in accuracy & rate of fire. Much like all Japanese Heavies, the O-Ni feels right at home in the city, where it can use cover to hide its numerous weak spots and safely complete long reloads. However, extreme care is needed when side-scraping as the side armor is thin and easily penetrated when over-angled, especially at the drive wheel. On top of that, the hull has angled "cheeks" which further inhibit the ability to side-scrape as angling will decrease their angle. Not only are the mini-turrets weak spots, but they also get in the way of the O-Ni's 10 degrees of gun depression, decreasing it to 9 degrees when aiming directly above them.
In regards to its cannons, the 15cm derp gun is a finicky gun, it has amazing damage potential against lower tiers, but is less effective against more properly armored higher tier opponents. It also has absolutely atrocious ability to snapshot - you can easily miss enemies completely from a close distance unless you wait (a long time) for the reticle to shrink completely. If you want a faster reloading gun with consistent DPM, ROF, and good penetration, the 10cm experimental gun is for you. Mobility should be kept in mind as O-Ni is very slow, therefore good planning of location and travel should be utilized as to not be left out.
Depending on the maps, team composition, and gun/cannon of choice, O-Ni can be easily played either as a frontline brawler or a conservative supporting tank, in that sense, it makes O-Ni a pretty interesting tank to play as it can play the role of a supporter, sniper, brawler and a huge meat shield very well, it all depends on an individuals playstyle on how they choose to play this tank.
In the hand of a skilled & knowledgeable player, the O-Ni can be a highly vicious tank to use/battle against. It often surprises in performance at times.
Early Research
Once you have acquired the O-Ni, you can mount the upgraded engine, second radio and 15cm derp inherited from the O-I. Next research the tracks to increase payload and traverse speed. Keep in mind you cannot fit the top 10cm experimental gun with the stock suspension along with the upgraded engine and radio. Research the top radio to boost signal range and finally work your way for the upgraded 10cm exp gun.

Historical Info
The "O-Ni" is based on misconceptions of the O-I super-heavy tank. Post-war speculations about the mysterious O-I resulted in that it was commonly accepted that there were at least two variants of the tank:
- 100 ton O-I, 3 turrets, built in 1941-1943 (known in-game as "O-Ni")
- 120 ton O-I, 4 turrets, built in 1944 and shipped to Manchuria. (known in-game as "O-Ho")
The 100 ton O-I supposedly mounted a 105 mm gun on it's main turret and have mini-turrets on front.
However, with more information now available to the public, it is known that all of this is false, and that there is only one version of the O-I - the ~ 150 ton O-I with a 15 cm howitzer (with the prototype being "only" 97 tons, as it lacked turrets, main armament and additional 75 mm armor plates).
The design of the 100 ton O-I is based on a very early sketch of the O-I. The speculations in return are based on an inaccurate description of the O-I. The weight for example comes from the incomplete prototype, which was just below 100 tons. The 100 ton O-I was said to have between 150 - 175 mm of armor and a 105 mm gun (which is likely results of mistranslation or -spelling of the 150 mm gun).

Historical Accuracy Errata
* O-Ni is based on the drawings from the book “Imperial Japanese Army Ground Weapon Guide 1872-1945”; those drawings in return are based on a very early sketch of the O-I super-heavy tank, combined together with false information and rumors like the usage of 10 cm Type 92 gun. As the drawings of "O-I 100t" are a very inaccurate representation of the O-I, it is safe to say that the O-Ni, the way it is in-game, never existed, not even as a project.
- In-game name is incorrect. The name "O-Ni" means "fourth (super) heavy tank". There is however no third super-heavy design, as the O-I was the first design, and Type 4/5 Heavies, if they existed, were the 2nd and last design. If the O-Ni actually existed, a more realistic designation would be "O-I II" (as the both O-I 100t and O-I 120t (O-Ho) are based on designs that were earlier designs than the Type 4/5, they most likely would have been referred to as "alternate" designs to the O-I - O-I 100t and O-I 120t as O-I II and O-I III, respectively).
