Sparn / スパーン
How to obtain: After suppressing Forestland (樹界), station Zanma Gou (斬真豪) and trigger the event to suppress the World Tree ("制圧：世界樹"). After a few turns when you see the events with the elves (necessary if you want to recruit Sonnet (ソネット)), don't trigger it. Keep waiting and eventually Sparn will H Sonnet (ソネット).

Mitamazuka Youki / 魂塚妖姫
How to obtain: Capture her while fighting in Shinjuku (真宿) (she can only be captured when they fight back after you first conquer the region, where she will try to re-take it; also, she will remain capturable and killable even if she regains control of Shinjuku). Persuade her once. Then be sure to have Touma Kanata (冬摩彼方) and talk to him twice in the Companion Phase, then persuade Mitamazuka again. (See notes)

Range: Medium

Bond: Hostile

Skill:
 * Inversion Mirror: 3 Stamina. Completely reflects the attack of the enemy, but doesn't work with long-ranged attacks.

Character Checks:
 * Speak to her three times in the Companion Phase.
 * After the previous star, in Sekiga Hara (関ヶ原), trigger the event "Youki Takes a Walk (妖姫の散歩)".
 * After the previous star, in Transylvania (トランシルバニア), trigger the event "Youki Takes a Walk (妖姫の散歩)".
 * Can only be done after the previous star. First of, be sure to station Zanma Gou (斬真豪) in Kumamoto (熊元) and then trigger the event "制圧：霊厳洞" that appears. Afterwards, station Mitamazuka in the region and trigger the event "妖姫の散歩".
 * About 20-30 turns after speaking to her for the second time, speak to her one more time. IMPORTANT! See notes below.

Other Notes:
 * CG [7-3-2] is obtained during her 5th star clear.
 * About the 5th star, if you haven't obtained the "Defense God (守り神様)" item, Zanma Rouga (斬真狼牙) will die after the scene, netting you a game over. The item can be obtained by stationing Zanma Gou (斬真豪) in the Shinjuku (真宿) region, also note that you only have one shot at this star (If you turn her down, she won't ask you again).
 * About her joining... If you have Asakura Yuma (朝狗羅由真) with you and Mitamazuka is still in prison, she will escape. However, it is possible to recruit Mitamazuka first then Asakura.
 * Mitamazuka Youki is necessary for Murakumo Shizuri's second star clear.

Touma Kanata / 冬摩彼方
How to obtain: Weird one. First one, you need to suppress Shin Juku (真宿). During the fights, you might encounter Mitamazuka Youki (魂塚妖姫), but you won't be able to capture her at this point. After you conquer the region and they fight back, you'll be able to capture her. Do so and station Zanma Gou (斬真豪) there to discover event "Visit Rice Cracker Store" ("煎餅屋訪問"). Trigger the event "Visit Rice Cracker Store" ("煎餅屋訪問")three* times after Youki have been killed or captured (sometimes it might not appear until a bit later) for him to join. Once you have conqured Shinjuku (真宿), the "Visit Rice Cracker Store" event will still be available even if you lose control of it. If you do not kill or capture Youki, she will prevent you from visiting the store.

''*This number appears to be random. I've had it take as few as 2 visits (2 turns to conquer, with capturing Youki on Independent turn of round 2, then visiting on turns 3 and 4) and as many as 5 visits (1 visit before capturing Youki and 4 after). Reader Note: Visits before capturing Shinjuku seem to be meaningless, but Touma Kanata will join from visits after capturing then losing Shinjuku.''

Range: Medium

Bond: Normal

Skill:
 * Ally Experience +10%: Passive. Increases the Exp obtained by 10% of all allies in the region after combat. The bonus increases to 20% on obtaining his 1st star.

Character Checks:
 * Speak to him 4 times in the Companion Phase.
 * This one is obtained before you recruit him. At one point while fighting the Shin Juku (真宿) region,' 'Zanma Gou (斬真豪) will provide information to you about Touma. Then, TWO events should happen (if not right away, in another turn) between Touma and Mitamazuka Youki (魂塚妖姫) when the Independent regions are taking their turn. Do not capture or kill Youki before both of these events or you will miss this star (you can keep bashing Mitamazuka Youki (魂塚妖姫) and her zombies, since she won't be killed or captured as long as Shinjuku has not been conquered). Note: It also seems that the event "Visit Rice Cracker Store" ("煎餅屋訪問") (before Mitamazuka Youki is captured or killed) increases the chance of the 2nd star event to happen (it raise the event priority in case it is being pushed back by other event).
 * Station him along with Mitamazuka Youki (魂塚妖姫) in the same region for an event on the next turn.
 * Station him along with Mitamazuka Youki (魂塚妖姫) in the Shin Juku (真宿) region for an event on the next turn. They have to be alone (no other units)

This BP bag should be picked up as soon as possible if you want cash for various things. (I'm not so sure about this note since I have activated it over EIGHT times in one playthrough. ( I stopped counting but he was a real moneybag) It may have something to do with time between each event or such, needs more reasearch.)

Skill:

Bond: Trust

Skill:
 * Ally Dodge +20: Increases the EVA of all allies in the region by 20.

 * Unlike other eyeless generic characters, it has a unique battle sprite set of a big fat penguin robot with a rocket backpack that don't resemble its picture at all.

Haniwa Soldier
How to obtain: In Dream Island (夢の島), convert to the Haniwa Cult. After you have visited the Haniwa Banquet for the first time, you can recruit a Haniwa Soldier as a event. Sometimes a Haniwa soldier will join you after the banquet. You can recruit a lot of them, if you want.

Range: Long

Bond: Trust

Skill:
 * None

Character Checks:
 * Haniwa Soldier has no character checks.

Other Notes:
 * CG [9-1-3] is obtained when you visit the Haniwa Banquet a couple of times.
 * CG [9-1-4] is obtained when you visit the Haniwa Banquet an additional couple of times.
 * Tenko might give you a Hanny Zippo (ハニージッポ), because she is worried about the recruited Hanny.
 * For beginners recruiting and using the haniwas might be a more easy way to get used to the game mechanics in the national chapter without worrying too much about payment and loyality.
 * That said, possible events during Rougas teams phase AKA beginning of turn phase (When Tenko comes to warn you about not visiting the banquet) and Territory phase (When actually going to the banquet) will be wasted, since those two events are top priority (due to the reason listed below), so keep that in mind before joining the cult.
 * If you don't visit the banquet after the Haniwa Priestess Maeda Tenko asks you to, which you have to on a regular basis as a follower of the Haniwa Cult, you will get a game over!
 * Haniho!

Ravi / ラヴィ
How to obtain:ONLY AVAILABLE IN HARD MODE! After conquering Forestland (or other obscene dream province from the list below), Gou will mention the province isn't generating income due to the obscene dreams during the start of a turn. Visit BS Finance again to recruit Ravi.

Territories with obscene dream girl: An event is automatically triggered after curing all the girls, follow the story from there and you should get a star event in Saporo. Do that and the last CG will be unlocked. The Japanese wiki seems to indicate that you have to pay back all your debts for the automated event to trigger. I had assumed that it triggers only on one condition and the debt was written off. (most likely need to pay off the debt for event to occure as the event occure around the next turn i paid off my debt)
 * Forestland
 * Shisuoka
 * Niigata
 * Abashiri
 * Kumamotou
 * Oka Yama
 * Saporo
 * Sekiga Hara
 * Nakoya
 * Nihon Bridge

Warning! The monsters in the obscene dreams are challenging to say the least unless weakened. Attempt the compulsory treatment without waiting for the infection level to drop and you might hit a Game Over. However, Sanzou, Youki, and some who has reflect-type skills can work wonder on this demon class. Pre-emptive strikes can also work, but not as elegant as the above tactic. Alternatively, use Sion's Tea Party, Amon/Saki and Ginjou. With all these boosts, Rouga and/or Kuga should have an EVA high enough to just not get hit, if you leveled them up a bit. You can easily clear 95%+ infection levels that way. Another strategy, since all the enemies only have 3 stamina each, waste their stamina male Yuuki's Boom and Yamamoto's Swift Dodge work great for early on, and when you get Takabane Sae her ability (avoid combat, all enemies -1 stamina) can really make it easy, especially if you five star her beforehand, then it's just a matter of between 5 characters having enough stamina/attack to deal about 600 damage (since enemies without stamina cannot evade or attack back)


 * Obscene Dream Monsters (Example@80% infection level)


 * 5x MID HP90-100 ATK120-140 EVA90-110 HIT70-80 CTR0


 * 1x LNG HP80-90 ATK50-60 EVA0 HIT120-130 CTR0
