Explanation
  1. Jupiter did not battle two days in a row (c1), so she battled on Monday, Wednesday, and Friday. Mars battled three days in a row (c1), so she battled on one set of: Monday, Tuesday, and Wednesday; Tuseday, Wednesday, and Thursday; or Wednesday, Thursday, and Friday. Any any possible set of Mars's battles (e1), she battled on Wednesday. Jadeite transformed a squirrel (c1), and Queen Beryl, whose creature mercury battled (c1), did not transform the fish (c1).
  2. Mars's second monster was not Jupiter's second monster (c2), which was on Wednesday (e1), so Wednesday was either Mars's first or third battle. Mars's second battle was not Tuesday (c2), but it was either Tuesday or Thursday (e2), so Mars battled on Wednesday, Thursday, and Friday. Because Mars's second battle was on Thursday (e2), because the only battle with both Jupiter and Moon, the one by Nephrite, and the one at the park were all neither Tuesday nor Mars's second battle (c2), and because Jupiter battled on Monday, Wednesday, and Friday (e1), Jupiter must have fought Nephrite's creature, have fought in the park, and have fought with Sailor Moon, no two of which were on the same day, which also means that Moon fought neither in the park nor again Nephrite's creature. Mars's second battle on Thursday (e2) was either downtown or at the lake (c2), so Thursday's battle was either at the lake or downtown.
  3. Mars and Venus battled alongside Jupiter twice (c3), but the team of Mars, Venus, and Jupiter could not have occured twice (c1), so one day of Monday, Wednesday, and Friday had a team of Mars, Venus, and Jupiter, one had a team of Mars, Jupiter, and another senshi, and one had a team of Venus, Jupiter, and another senshi. Mars did not battle Monday (e2), but Jupiter, who battled on Monday (e1), fought alongside Mars or Venus, if not both, in every battle (e3), so Venus battled on Monday, on either Tuesday or Thursday, and on either Wednesday or Friday. Queen Beryl's creature never fought Jupiter (c3), so it appeared on either Tuesday or Thursday. Jupiter never fought at the temple (c3), so the battle at the temple occured on either Tuesday or Thursday, but, because Thursday's battle was not at the temple (e2), the temple fight happened on Tuesday. Neither Mars nor Mercury battled Zoicite's creature (c3), so it was fought by Moon, Jupiter, and Venus.
  4. The set of Mercury, Venus, and Moon occurred (c4), not in Monday's, Wednesday's, or Friday's battles, which included Jupiter (e1), and not on Thursday's, which included Mars (e2), so Mercury, Venus, and Moon battled together on Tuesday. Because one of Venus's battles was on either Tuesday or Thursday (e3) and because one was on Tuesday (e4), it was not on Thursday. Because Jupiter (e1) and Venus (e4) did not battle on Thursday, Mars, Mercury, and Moon did. Mercury, Venus, and Moon battled together on Tuesday (e4), and the spider did not appear the day after (c4), so the spider did not appear on Wednesday. Mercury battled on three consecutive days (c4), and fought on Tuesday (e4) and Thursday (e4), so she must also have fought on Wednesday but not Monday or Friday. Becauser Mercury (e4), Mars (e2), and Jupiter (e1) all fought on Wednesday, Venus did not. Venus fought on Monday (e3), Tuesday (e4), not Wednesday (e4), and not Thursday (e4), so she fought on Friday. Because Jupiter (e1) and Venus (e3) fought on Monday and because Mars (e2) and Mercury (e4) did not, Moon must have been the third participant in Monday's battle. Zoicite's creature battled Moon, Venus, and Jupiter (e3), who fought together on Monday (e4), so Zoicite attacked on Monday. Mercury did not battle the spider (c4), and she fought on Tuesday, Wednesday, and Thursday (e4), so the spider attacked on either Monday or Friday.
  5. Jupiter (e1) and Moon battled together on Monday (e3), Tuesday (c2) was on Tuesday, the second monster defeated by Rei was on Thursday (e2), and, since these three battles were neither the one at the park not the one against Nephrite (c2), the battle against Nephrite and the battle at the park occurred on Wednesday and Friday, in no particular order. The battle at the temple happened before the one at the arcade (c5), so the arcade battle was not on Monday. The battle at the lake happened before the one downtown (c5), so the battle downtown was not on Monday. Since Monday's battle was not at the arcade (e5), downtown (e5), at the park (e5), or at the temple, which was on Tuesday (e3), Monday's battle had to have taken place at the lake. Because the downtown and temple battles did not occur on consecutive days (c5), and the temple battle happened on Tuesday (e3), the downtown battle was not on Wednesday. Because Thursday's battle, Mars's second (e2), was fought either downtown or at the lake (c2), but not at the lake, where the senshi fought on Monday (e6), Thursday's battle was downtown. The one where Nephrite transformed a creature was not the same as the one at the park (c2); they both happened on either Wednesday or Friday (e5); the arcade battle was not on Monday (e5), Tuesday, the day the temple was attacked (e3), or Thursday, the day a battle happened downtown (e5) and so was on Wednesday or Friday; and the park battle was not on Monday (e5), Tuesday, the day the temple was attacked (e3), or Thursday, the day a battle happened downtown (e5) and so was on Wednesday or Friday; so Nephrite attacked the arcade.
  6. Jupiter never fought a creation of Queen Beryl (c3), and Jupiter battled Monday, Wednesday, and Friday (e1), so Queen Beryl attacked either Tuesday or Thursday. Jadeite attacked the day before Queen Beryl (c1), so either Monday or Wednesday, but not Monday, the day Zoicite attacked (e4), so Jadeite transformed a creature on Wednesday and Queen Beryl on Thursday. Since Nephrite attacked either Wednesday or Friday (e5), but Jadeite attacked Wednesday (e6), Nephrite attacked on, and, consequently, the battle at the arcade happened on (e5), Friday. The park battle was on Wednesday or Friday (e5), but the arcade fight was on Friday (e6), so the park battle happened on Wednesday. Tuesday's battle did not involve Jadeite, who attacked on Wednesday (e6), Nephrite, who attacked on Friday (e6), Queen Beryl, who attacked on Thursday (e6), or Zoicite, who attacked on Monday (e4), so Tuesday's attack was instigated by Kunzite. Because Jadeite attacked on Wednesday (e6), and Jadite transformed a squirrel (c1), the squirrel was transformed on Wednesday.
  7. The spider was fought on either Monday or Friday (e4), the squirrel attacked on Wednesday (e7), and the snake was fought before the fish, which was fought before the crow, (c5), so the battles against the snake, fish, and crow happened either on Monday, Tuesday, and Thursday or on Tuesday, Thursday and Friday, respectively, with the spider's attack on Friday or Monday, respectively. Queen Beryl attacked on Thursday (e6), and she did not transform the fish (c1), so the fish was not transformed on Thursday. Since Monday, Tuesday, Thursday, and Friday have the creature options of either spider, snake, fish, and crow or snake, fish, spider, and crow, respectively (e7), but the fish was not fought on Thursday (e7), the battles on Monday, Tuesday, Thursday, and Friday must have been against the snake, fish, crow, and spider, respectively.
