Technically not an anime, but a game with anime art. And technically more of a visual novel than a full fledged game. I didn't want to make a new thread.

Amazing game. Here are my slightly revised estimates, from what I posted recently in the video games thread:
Ace: iNTJ 8w9-3w-5w6 sp/so
Snake: INTP 5w4-9w1-3w4 so/sp
Santa: xSTP 7w8-8w7-3w4 sx/sp
Clover: ESFP 7w6 or 6w7-4w3-8w7 sx/so
Junpei: ExTP 8w7 or 6(w either wing)-2w1 so/sp
June/Akane: INFP 9w1-6w5-2w1 sx/so
Seven: ESFJ? 7w6?-1w2-2w1? So/sp
Lotus: ISTP 4w3-8w7-5w4 sp/sx
Kubota/9th Man: ISTJ? 6w5 sp/so
Ace: I could see either xNTJ here (the xNTJ is obvious). I don't think a clear argument can be made for either one - he uses people as means to his ends, and is pretty much forced to interact with the other characters throughout the game just as they are. He comes off as relatively friendly but beyond that mask we don't really know what his natural preference is. As for Enneagram, I would say 8w9. He's too patient, calm, and "steady" to be 8w7. He exudes that reserved strength of the 8w9 rather than the more overt assertiveness of an 8w7. Even after he goes into open villian mode and admits everything.
Snake: I could see INFJ for Snake, it would be my second guess. The INxx and Ti are pretty obvious for him, at least. The flashback seen from 9 years before when he calmed down the other kids and handed out the four-leaf clovers also points to INFJ over INTP. 5w4 vs 9w1 is a close call as well, I'll admit.
Santa: ESTP 7w8 sx/sp Santa is abrasive, outspoken, and edgy. He also acts independent. There is no way he's a 2. What about him would make you guess 2? If you're referring to his relationship with his sister, that protectiveness and care needn't be attatched to type. After being orphaned, wouldn't it be natural for an older brother to look out for and care for his innocent younger sister, and especially so when she's in danger? His attatchment to her speaks of him being sx dom more than anything else. The fact that he's xSTP is pretty obvious, but the above traits also point to extraversion (and 7w8). ISTP would be my second guess though.
Clover: Ok, I could see her as a 4. If so, she's definitely 4w3. Clover just acts more extraverted than most 4s (although the moodiness fits), and has the cheerfullness/excitibility of a 7.
Junpei: ExTP 8w7: Junpei can obviously be characterized differently depending on the players choices, but throughout the game, and during the major scenes which you have little to no control over he acts quickly, decisively, and "gets things done" - all 8 traits. Despite being far from having seniority in the group Junpei naturally takes charge in many scenes and acts as a catalyst. He is also analytical and observant, which points to Ti (he is the one solving all those puzzles almost single-handedly, after all, and under pressure). I'm curious as to why you chose 4 for him (and ENFP to a lesser extent), as I see no trace of 4 in him whatsoever.
June: Assuming her observable personality and actions throughout the game were not a total facade, June is archetypal of an INFP 9w1. She is quite timid, easygoing, and unassertive unless someone suggests something that goes against her humanistic values (or her plan, I suppose), and has an active imagination, loving supernatural explanations for things. She also lets on much less than she knows (primarily in order to recreate her vision), but nevertheless this is in my opinion a common INFP trait. Most of all I feel that she is not at all an extravert, a prime trait of 2s. INFJ is the only other type I could see her as.
Seven: ESFJ 7 (either wing): From the start I wasn't sure of Seven's type except that he was certainly ESxx. After considering your typing of ISFJ I decided he does seem to be what an xSFJ male cop would look like, but he's definitely extraverted, probably the most extraverted of all the characters except possibly Clover. The Si is apparent in his highly observant nature and natural detective skills. He's often making lighthearted jokes and acting relatively hedonistic the way a 7 would. Admittedly, his forgotten past as a cop determined to see justice does fit 1 better than 7, but if he were a 1 I would definitely type him as a 1w2. He's not at all remote the way a 1w9 would tend towards being. He's very enthusiastic and expressive; more emotional and people-oriented like a 2 rather than the more stoic, calm 1w9.
Lotus: 4w3: Initially my guess was ESTP or ISTP for Lotus, the T being the only thing I was confident of, but INTJ is an interesting possibility. Why do you think so? As for Enneagram, I thought 3w4 at first but Thunderbringer convinced me 4w3 was a better fit. As he said, she has a flair for the dramatic from how she was dressed to her behavior throughout the game (the conversation between her, June, and Junpei in the hallway while looking for Snake comes to mind, along with her subsequent "proposal" about sacrificing someone in the hospital room). Also, her voluntary choice behind door 2 shows the defeatist side of 4. I'm curious, what makes you think 5w4 for her?
9th man: ISxJ 6w5: While we probably don't get to observe the 9th man for long enough to get a good guess at his type, his complete willingness to trust Hongou, his former (current?) associate and boss is something very uncharacteristic of the questioning, independent-minded 5. It can be a 6 trait however (as well as an ISxJ trait, hence my guess), and he *really* comes off as an unhealthy 6 in his defining scene; radiating paranoia, anxiousness, and putting all his hope in someone he thinks he can trust (Hongou). He seems like a very nervous person in general, characteristic of 6s, not 5s.
