Once Yūichirō and Sunday have reappeared on the screen, their ships will start flying forward as two groups of Hanbaga come zigzagging towards them; once you fire a shot at each of them to kill them, then collect those 1000 Crystals they have left behind, eight Heri will come flying towards you while firing projectiles at you.
Once you've fired a shot at each of these to kill them, Miyuki Chan's Kūchū IN passes by - and for a seventh time, when one player enters it, the other will automatically be drawn in as well. The first player will then have 20 seconds to choose between a 3-way shot (for 18000 crystals), an After shot and Speed-up for 22000 crystals, and a Fire bomb and Speed-up for 18000 crystals; the best choice would most likely be the After shot and Speed-up, as it's ten times more powerful than the normal shots and will increase the flying speed of your ship.
Once Yūichirō has paid Miyuki for his chosen item, the pictures on the screens will change and the second player will have 20 seconds to choose between: a Stock bomber shot for 12000 crystals, a Homing missile and Speed-up for 15000 crystals, and a Subroc bomb (which are again not available to 1P) for 11000 crystals - and the best choice would now most likely be the Homing missile and Speed-up, as it will automatically home in on any enemies that are currently on the screen, and increase the flying speed of your ship.
Once Sunday has paid Miyuki for his chosen item, he and Yūichirō will fly back out of the Kūchū IN and continue onward; fourteen more Heri will then come flying towards you while firing projectiles at you.
Once you have fired a shot at each of them to kill them, you will come up to two Maru Hodai that are firing projectiles at you from their positions on a rock with a windmill on it - and if you fire a shot at this windmill's sails from the top, they will start rotating clockwise. However, if you fire a shot at them from the bottom, they will start rotating anticlockwise and make it impossible for you to pass over it without getting hit; once you have made it to the other side, you will come to a third Maru Hodai that is firing projectiles at you.
Once you have dropped a bomb on it (or, if 1P, fired an After shot at it from behind) to kill it, you'll come to a Tako, that is moving up and down in a fixed position.
Once you have fired enough shots at it to kill it, you will come to a Kiwi Base on the floor of the ocean below, which will open up and the Kiwi inside will be released in groups of four, flying directly towards Yūichirō and Sunday once they have reached their altitude.
Once you have dropped enough bombs on the base to destroy it you will come to four more Tako which are moving up and down in a fixed position.
Once you have fired enough shots at all four of them to kill them, two more Heri will come flying towards you while firing projectiles at you. Once you've fired a shot at both of them to kill them, you will come to another rock with six more Maru Hodai firing projectiles at you from their positions and another windmill on it - and once you've fired a shot at each of the Maru Hodai to kill them, you will have to fire a shot at that windmill's sails from the top to make them start rotating clockwise, for if you fire one at them from the bottom, they will start rotating anticlockwise, and again make it impossible for you to pass over without getting hit.
Once you have made it to the other side, you will come to deal with a tenth Maru Hodai that is firing projectiles at you; once you have dropped a bomb on it (or again if 1P, fired an After shot at it from behind) to kill it, you will come to a second Kiwi Base.
Once you have dropped enough bombs on it to destroy it, you will come to three more Tako moving up and down in a fixed position - and once you have fired enough shots at each of them to kill them, you will come to a third another rock with two more Maru Hodai firing projectiles at you from their positions and a third windmill on it.
Once you've fired a shot at both of the Maru Hodai to kill them you will have to fire a shot at the windmill's sails from the top (to make them start rotating clockwise); if you fire a shot at them from the bottom, they will start rotating anticlockwise and once again make it impossible for you to pass over it without getting hit.
Once you have made it to the other side, you will come to a third Kiwi Base at the bottom of the ocean; once you have dropped enough bombs upon it to destroy it, Dream Co., Ltd. will pass by. Once again, when one player flies into him, the other will automatically be drawn in as well - and Dream Co., Ltd. will now speak a Kanji/Hiragana text Watashi ha DREAM CO., Ltd. 2000 kurisutaru ī mono ga ataru yo. 1P no kata chōsen shite mina ika? (私は DREAM CO., Ltd. 2000クリスタルいいものが当たるよ. 1Pの方挑戦してみないか?) to the first player. If his answer is "yes", he'll extend his target and speak the Kanji/Hiragana text Yō shide ha 3-byō-go ni botan wo sunda!! (よーしでは3秒後にボタンをすんだ!!) as it starts rotating; after three seconds, you must press the Firing Button to launch your marble at the target, and the table upon the left side of the screen shows what you will win for each number. 1: After shot (アフターショット), 2: 100000 crystals, 3: Stock bomber shot (ストックボンバー), 4: 5000 crystals, 5: Homing missile (ホーミングミサイル), 6: Nothing, 7: Fire bomb (ファイヤーボンブ), 8: 20000 crystals.
Once your marble lands on his target (you may have noticed that the set-up is identical to the previous round) he'll retract it and speak the Hiragana/Katakana text Omedetō!! Afutā shotto/100000 kurisutaru/Sutokku bonbā/5000 kurisutaru/Hōmingu misairu/Faiyā bonbu/20000 kurisutaru. (おめでとう!! アフターショット/100000クリスタル/ストックボンバー/5000クリスタル/ホーミングミサイル/ファイヤーボンブ/20000クリスタル) if it landed on 1, 2, 3, 4, 5, 7 or 8, or the Kanji text Zan'nen (残念) if it landed on 6 - and if it had landed on 1, 3, 5, or 7, Dream Co., Ltd. will speak that Kanji/Hiragana text Kono buki ha sugu tsukaimasu ka? (この武器はすぐ使いますか?) to the first player, and if you answer "no", you'll receive it the next time you are killed. He will then speak the Kanji/Hiragana text 2P no kata chōsen shite mina ika? (2Pの方挑戦してみないか?) to the second player; again, if he answers "yes", he'll extend his target and speak the Kanji/Hiragana text Yō shide ha 3-byō-go ni botan wo sunda!! (よーしでは3秒後にボタンをすんだ!!) for the second time as it starts rotating. After three seconds, you must press the Firing Button to launch your marble at the target - and the table on the left side of the screen shows what you will win for each number. 1: After shot (アフターショット), 2: Fire bomb (ファイヤーボンブ), 3: 20000 crystals, 4: Nothing!, 5: 100000 crystals, 6: Stock bomber shot (ストックボンバー), 7: 5000 crystals, 8: Homing missile (ホーミングミサイル).
Once your marble has landed on his target (again, you may have noticed that its set-up is identical to the previous round), he'll retract it and speak that Hiragana/Katakana text Omedetō!! Afutā shotto/Faiyā bonbu/20000 kurisutaru/100000 kurisutaru/Sutokku bonbā/5000 kurisutaru/Hōmingu misairu (おめでとう!! アフターショット/ファイヤーボンブ/20000クリスタル/100000クリスタル/ストックボンバー/5000クリスタル/ホーミングミサイル) if it landed on 1, 2, 3, 5, 6, 7 or 8, or that Kanji text Zan'nen (残念) if it landed on 4; if it landed on 1, 2, 6 or 8, Dream Co., Ltd. will speak that Kanji/Hiragana text of Kono buki ha sugu tsukaimasu ka? (この武器はすぐ使いますか?) to the second player, and if your answer is "no", you will also receive it the next time you are killed. He will then speak that Kanji/Hiragana text Mata no chōsen wo matsu teru yo. (またの挑戦を待つてるよ) to Yūichirō and Sunday as they exit his realm and continue onward as three Sensuikan propel themselves through the ocean below while firing missiles into the air.
Once you have dropped enough bombs on each of them to kill them, they will come to two gray blobs (which will eventually metamorphosize into Big Heri). Once you have fired enough shots at both of them to kill them and collected the Crystals they have left behind, R-4B comes down on you from above.
Once you've fired enough shots at each of its nine front-mounted laser-firing cannons to destroy them, you will have to aim for the double-sided core (which can be hit from the front with any type of shot, but can only be hit from behind if you won the After shot from Dream Co., Ltd. beforehand). Once you have fired enough shots at the core to destroy it, it explodes and sinks down to the bottom of the ocean. Round Clear Bonus: 10000 Round Clear Bonus Crystals: 20000. It is also worth noting that the technical naming for those three windmills is Kazaguruma, written in Kanji as 風車.
