Q1: Can this card's digivolution requirements evolve from "Takuya Kanbara" with more than 5 cards with "Hybrid Body" in the trait below, with an evolution cost of 5?
Yes, it can digivolve.
Q2: When an opponent's Digimon is made to disappear in a battle in which this card, which has gained "Penetrate" by the effect of another card, attacks, does it check with "Penetrate" after this card's Your Turn effect is activated?
Yes, it activates. and then checks with "Penetrate". This card's Your Turn effect and "Penetration" are triggered at the same time, but the activated "Penetration" is processed just before the End of Attack, so the "Penetration" is checked after the "S Attack +1" is obtained by this card's Your Turn effect.
Q3: The situation is that you evolved from "BT18-088 Takuya Kanbara & Koji Minamoto" to this card, and its memory is more than 1 on the opponent's side. At this time, I attacked with this card's When Digivolving effect and became active with this card's Your Turn effect. After that, can I attack a player with the When Digivolving effect of End of Your Turn of this card's BT18-088 Takuya Kanbara & Koji Minamoto, which is the digivolving card?
Yes, you can attack. Until you digivolve to this card and resolve all the processes caused by it, you still do not meet the End of Turn condition. In this situation, all When Digivolving and End of Your Turn effects of this card and the effects caused by them are resolved, and the End of Turn condition is satisfied. After that, it becomes End of Turn, and the End of Your Turn effect of "BT18-088 Takuya Kanbara & Koji Minamoto" is triggered.
